Overview
Abra is a stablecoin protocol being built on Robinhood Chain. Its idea is small enough to say in one sentence: a coin that earns trading fees should be able to turn those fees into a reserve, and that reserve should mint a stablecoin one for one.
A coin is launched through the Pons launchpad. Abra pairs it with a companion stablecoin that has its own vault and gateway. The creator fees the coin earns on Pons are claimed by a keeper roughly every 10 minutes, converted into the reserve asset and deposited into the vault, which mints the stablecoin against that deposit. Holders can also mint it themselves by depositing the reserve asset directly.

The protocol has three moving parts, and the rest of this page follows them in order:
- A launch on Pons — a fixed-supply coin on an ETH bonding curve. Pons runs this part; its parameters are Pons’s, not Abra’s.
- A stablecoin stack per pair — stablecoin, vault and gateway, with the backing asset fixed at launch.
- A keeper — an off-chain operator that claims the creator fees, converts them and deposits them, so the reserve grows without anyone pressing a button.
Concepts
The vocabulary the rest of this page uses. Nine words carry the whole design.
Pair & tokens
- Pair
- One launcher token plus its companion stablecoin, with a vault and a gateway of their own. Every Abra launch creates exactly one pair, and the two halves stay tied together: the coin earns the fees, the stablecoin is what those fees become.
- Launcher token
- The ordinary, volatile coin created through Pons — for Abra’s own pair, $ABRA. It trades on a bonding curve and then on a Uniswap pool, and it is the source of the creator fees.
- Companion stablecoin
- The second token of a pair — for Abra’s own pair, $ “the stablecoin”, an ERC-20 with 6 decimals. Only its vault can mint it, and only against a deposit of the backing asset. A USDG-backed companion targets one US dollar; one backed by another approved asset tracks that asset instead.
- Pons
- The launchpad on Robinhood Chain that Abra builds on. It is non-custodial — your wallet submits the transaction — and every launch is a fixed supply of 1,000,000,000 tokens. Abra does not operate Pons. See the Pons v2 docs.
- Bonding curve
- Pons’s launch market. The whole supply is minted to the curve, the price rises with buys and falls with sells, and a 1% fee is charged on every trade in the quote asset.
- Graduation
- The moment a Pons curve completes — at 4.2 ETH — and its reserves move into a full-range Uniswap v4 position that stays locked. Trading continues there and the fee keeps accruing, charged by the Pons hook instead of the curve.
Vault, gateway, backing
- Vault
- The per-pair contract that holds the backing asset and mints the companion stablecoin one for one on deposit. It is the only minter, so the stablecoin’s supply cannot exceed what has been deposited.
- Gateway
- The per-pair router that accepts ETH: it swaps ETH into the reserve asset, deposits it into the vault and sends the freshly minted stablecoin to the caller — one transaction instead of three.
- Backing asset
- The reserve a stablecoin is minted against, chosen once from the protocol-approved list and fixed for the life of the pair. USDG is the default; 26 assets are approved in total. See Backing assets.
- Collateralization
- Reserve ÷ stablecoin supply. Because the vault mints only against deposits, the ratio is one to one by construction rather than by promise: it is a consequence of the minting rule, and anyone can check it by comparing two public numbers on the explorer once the contracts exist.
Keeper & fee cycle
- Keeper
- The off-chain operator that runs the fee cycle. It holds no user funds and mints nothing itself — it sends the transactions that claim, convert and deposit. If it stops, fees simply wait where they are.
- Fee cycle
- One run of claim → convert → deposit → mint, scheduled every 10 minutes. A cycle with nothing to claim ends immediately and costs nothing but gas.
- Sweep
- On Pons, the step that moves accrued trading fees out of the curve or the pool hook and into the fee escrow where the creator can claim them. Abra depends on that timing and does not control it.
How a pair launches
Abra does not run a launchpad. The coin half of a pair is launched through Pons v2, on Pons’s terms, and the parameters below are Pons’s published ones.
The Pons v2 flow
A Pons v2 launch mints a fixed supply of 1,000,000,000 tokens to a bonding curve quoted in ETH. Buys push the price up, sells push it down, and every trade pays a fee in the quote asset. When the curve fills, the token graduates: its reserves move into a full-range Uniswap v4 position that is locked, and trading continues on that pool. The creator’s share of the fee accrues in ETH and is claimed from the Pons fee escrow.
| Pons v2 parameter | Value | Notes |
|---|---|---|
| Supply | 1,000,000,000 | Fixed, minted to the curve at launch. |
| Launch fee | 0.0005 ETH | Paid to Pons when the token is created. |
| Trade fee | 1% per trade | Charged in the quote asset; the creator’s share is what a pair lives on. |
| Graduation | 4.2 ETH | The curve completes and its reserves move into a locked Uniswap v4 position. |
| Creator fees | Paid in ETH | Accrue to the creator-fee recipient set at launch and are claimed from the Pons fee escrow. |

What Abra adds
On top of that launch, a pair needs three contracts of its own — the stablecoin, its vault and its gateway — plus one arrangement that makes the whole thing work: the coin’s creator-fee recipient is set so that the keeper can claim those fees later and route them into the vault.
- The coin is launched on Pons
Fixed supply, ETH curve, Pons’s fee. This is the part Pons does.
- Its stablecoin stack is deployed
The companion stablecoin, the vault that will hold the reserve, and the gateway that routes ETH into it. The backing asset is chosen here and cannot be changed afterwards.
- Fees are pointed at the vault
The creator-fee recipient is set so the keeper can claim the coin’s fees and deposit them. From then on the pair runs on its own.
What it costs
- The Pons launch fee — 0.0005 ETH, paid to Pons.
- Your optional first buy — whatever you choose to buy of your own coin at launch, in the quote asset.
- Gas — ordinary Robinhood Chain gas for the launch and the stack deployment.
Abra charges nothing today, because nothing of Abra’s is deployed. Any fee the protocol takes will be visible in the deployed contracts and stated here at launch.
The stablecoin and its vault
One rule does all the work: the vault mints one unit of the stablecoin for every unit of the backing asset deposited, and nothing else can mint.
The minting rule
A pair’s vault holds exactly one asset — the one chosen at launch, USDG by default. When that asset is deposited, the vault mints the same number of units of the companion stablecoin to the depositor’s address. There is no other minting path: not for the team, not for the keeper, not for a governance vote. Supply therefore cannot run ahead of the reserve, and the ratio between them is not a target that has to be defended, it is an accounting identity.
- Deposits come from two places: the keeper’s fee cycles, and anyone minting directly (see Minting).
- The stablecoin carries 6 decimals, matching USDG.
- The reserve sits in the vault contract, on chain, readable by anyone — not with a custodian, not in a spreadsheet.
What “backed” means, and what it does not
It means that the units in circulation were each minted against a deposit that is still in the vault, and that you can verify this yourself once the contracts are live by comparing the vault’s balance of the backing asset with the stablecoin’s total supply.
It does not mean a promise from Abra. A USDG-backed stablecoin targets one US dollar because USDG is a dollar stablecoin issued and redeemed by Paxos — the peg belongs to USDG, not to Abra. A stablecoin backed by GLD or by a Robinhood Stock Token follows the price of that asset and is not a dollar at all. And “backed” says nothing about the launcher token in the same pair: that half is a volatile coin, with the risks a volatile coin has.
Minting
Two routes into the companion stablecoin: deposit the reserve asset for a one-to-one mint, or deposit ETH and let the gateway do the conversion in one transaction.
USDG route — USDG → vault →
You deposit the backing asset and receive the stablecoin one for one. Nothing is quoted and nothing can slip, because no price is involved. At most two wallet confirmations:
ETH route — ETH → USDG → vault →
Available for backing assets that have a native swap route (today USDG and GLD). You send ETH and the gateway does the rest in a single transaction:
The two guards are the point of the route: a 1% cap means you cannot be filled at an arbitrary price, and a 300-second deadline means a stuck transaction expires instead of executing an hour later at a price you never saw.
What works today
The quote does. Everything in the ETH route up to the wallet — the QuoterV2 call on the live WETH/USDG pool — is a real chain read you can make right now, and the how it works page shows one. The deposit does not: it needs a vault address, and there is none until launch.
Fee cycles and the keeper
The mechanism that makes a pair’s reserve grow while nobody is watching: every 10 minutes, whatever Pons has released is turned into reserve.
The cycle
- Claim
The keeper claims the pair’s creator fees — ETH — from the Pons fee escrow. If Pons has released nothing since the last run, the cycle ends here.
- Convert
The claimed ETH is swapped into the pair’s backing asset on the Uniswap v3 pool (the 0.01% WETH/USDG tier for USDG pairs), with a minimum output and a deadline, like any other swap.
- Deposit
The proceeds are deposited into the pair’s vault.
- Mint
The vault mints the same number of units of the companion stablecoin against that deposit. Reserve and supply rise together, which is the only way either of them ever moves.
Every step is an ordinary public transaction on Robinhood Chain: once a pair is live, each cycle can be read on the explorer rather than taken on trust.
Why the timing depends on Pons
Fees do not arrive continuously. On Pons they accrue on the curve before graduation and on the pool hook after it, and they only become claimable once they have been swept into the fee escrow. After graduation that sweep is Pons’s to run, not Abra’s. So a cycle can find nothing to claim several times in a row and then find a batch at once — the 10-minute schedule is how often Abra looks, not how often Pons pays.
Backing assets
A companion stablecoin can only be minted against an asset on the protocol’s approved list: USDG, GLD and the Robinhood Stock Tokens.
The approved list
| Symbol | Name | Address | Decimals | Pons pair | ETH route |
|---|
Pons pair means the asset can also be the quote asset of the Pons curve, so the coin’s fees accrue in it directly. ETH route means the gateway can convert ETH into it automatically — today only USDG and GLD have that route; a pair backed by anything else takes its deposits in the asset itself.
Rules
- A USDG-backed stablecoin targets one US dollar. A stablecoin backed by any other approved asset tracks that asset and is not pegged to a dollar.
- The backing asset is chosen once, at launch, and cannot be changed afterwards.
- If the backing asset has no ETH route, the coin is paired against that same asset on Pons, so its fees back the companion directly with no conversion step.
USDG is the Global Dollar, a dollar stablecoin issued and redeemed by Paxos. GLD tracks the SPDR Gold Trust. The rest are Robinhood Stock Tokens: ERC-20s issued by Robinhood that give economic exposure to US shares and ETFs. They are not shares, they are not offered everywhere — the issuer’s jurisdictional restrictions apply to them and, through them, to any stablecoin backed by one.

Live today
These are the chain’s own infrastructure and the Pons launchpad. Abra reads them; it does not operate any of them. Each row links to the explorer and has a copy button.

Abra’s own contracts
None of these exist yet. There is no address to publish, and this site will not print a placeholder that looks like one.
| Contract | Address | Status |

When they are deployed, their addresses go into this site’s configuration and every page — this one, the vault page, the footer — starts showing them and the figures that come with them. Until then each slot reads SOON. Be careful with anything that claims otherwise: an address posted somewhere else before launch is not Abra’s.
Fees
Pons charges for launching and trading. Abra charges nothing today, because nothing of Abra’s is deployed.
Pons
| Fee | Amount | Notes |
|---|---|---|
| Launch fee | 0.0005 ETH | Paid once, when the coin is created. |
| Trading fee | 1% per trade | Charged on the curve and, after graduation, by the Pons hook. |
| Creator share | Set by Pons | The creator’s part of the trading fee is what a pair’s reserve is built from. The split is Pons’s — see their docs. |
Abra
| Fee | Amount | Notes |
|---|---|---|
| Protocol fee | None today | Nothing is deployed, so nothing can be charged. Any fee the launched contracts take is stated here at launch. |
| USDG deposit | One for one | The minting rule itself has no spread: one unit deposited, one unit minted. |
| ETH route | Pool fee + slippage | The Uniswap 0.01% pool fee on the ETH leg, plus up to 1% slippage against the quote, plus gas. These are the route’s costs, not a charge by Abra. |
Risks and disclosures
Read this before you decide to care. Nothing here is financial advice.
- Abra is pre-launch and unaudited. The contracts described on this page are not deployed and have not been reviewed by a third party. Nothing on this site has been proven by running.
- Launcher tokens are volatile and can lose all value. The coin half of a pair trades on a bonding curve and then on an open pool. The companion stablecoin does not protect it, and it does not back the companion.
- A stablecoin is only as good as its reserve and the asset that reserve is made of. The one-to-one minting rule guarantees that units were issued against deposits. It cannot guarantee what those deposits will be worth.
- USDG is issued and redeemed by Paxos, not by Abra. Holding a USDG-backed stablecoin is not a claim on Paxos and gives no right to redeem USDG from them.
- Stock-Token-backed pairs are not dollar-pegged. They track the token they hold, and they carry the issuer’s jurisdictional restrictions — those tokens are not offered to everyone, everywhere.
- The keeper is an off-chain operator. It is a piece of infrastructure that can be paused, throttled or fail. When it does, fee cycles stop until it is running again.
- Fee cycles depend on Pons sweeps. Fees become claimable when Pons releases them; after graduation that timing is Pons’s. A pair’s reserve can therefore grow in bursts, or not at all while trading is quiet.
- Vault administration is a real power. A vault that can be paused or migrated is a vault someone controls. The exact roles and who holds them are readable in the deployed contracts — check them at launch rather than taking this page’s word.
- Treat every address you see before launch as false. There is no $ABRA contract, no pair and no market yet. Anything claiming to be one is not.
FAQ
Short answers to what people ask first.
Is $ABRA live? Where is the contract address?
No, and there is not one yet. $ABRA has not launched: no token, no pair, no market. The address will be published here and across the site the moment it exists — every slot that will hold it currently reads SOON.
What is a companion stablecoin?
The second token of a pair. It is minted only by its vault, only against a deposit of an approved backing asset, one unit for one unit. Abra’s own companion is $, “the stablecoin”, backed by USDG.
Where will the reserve come from?
From trading fees. Every trade on the launcher token pays the Pons fee; the creator’s share is claimed by the keeper, converted into the backing asset and deposited into the vault, which mints the stablecoin against it. Anyone minting directly adds to the reserve the same way.
Will $ be pegged to a dollar?
It targets one US dollar because it is backed by USDG, a dollar stablecoin issued by Paxos — the peg is USDG’s. Pairs backed by another approved asset track that asset and are not dollar-pegged.
How will I mint it?
Two routes, both opening at launch: deposit USDG for a one-to-one mint, or deposit ETH and let the gateway convert and deposit it in a single transaction, with a 1% slippage cap and a five-minute deadline.
Can a pair be backed by something other than USDG?
Yes — any of the 26 approved assets: USDG, GLD or a Robinhood Stock Token such as NVDA, TSLA or SPY. The choice is made at launch and is permanent, and a non-USDG pair is not a dollar stablecoin.
What can I check today?
The chain. Robinhood Chain is live, USDG exists and has a public supply, and the ETH → USDG quote the mint route will use is a real read from the Uniswap v3 quoter. The how it works page shows all three.
Who runs the keeper?
Abra does, off chain. It holds no user funds and cannot mint: it only sends the claim, convert and deposit transactions, all of which are public and all of which anyone can read on the explorer once a pair is live.
