Real currencies, priced and settled onchain.
Rates come from an onchain oracle. Every leg settles on the chain you are using, with no bank rail or off-ramp in between.
Atomic swaps
One transaction. It completes or it reverts.
A swap between two currencies runs as a single transaction. If any step fails, the whole swap reverts and your funds stay where they were.
Under the hood
What happens inside one swap.
1 USDC in, 1,390 cNGN out. Deposit, split, swap, combine and redeem all happen inside the same transaction.
Live on testnet
Four currencies, each a real domestic stablecoin.
