BlockFinaX is currently migrating from Base to Stellar. Stellar is built for payments: stablecoins settle in seconds for a fraction of a cent, anchors connect them to local currencies, and accounts can be secured with passkeys. It also has a local presence and community in the markets we serve, and engages with their regulators. So it makes more sense for us, for now, to build on Stellar alone: running on one network concentrates all underwriting capital in one place, so pools are deeper and protection is better priced (see one liquidity hub ).
This page shows what already runs on Stellar, the status of each part, and where to find it: deployed contracts link to the Stellar explorer, where their code can be inspected, and services to the public BlockFinaX repository.

All contracts are written in Rust for Soroban, Stellar's smart contract platform.

Verified code. The code running at the currency pool address has the WebAssembly hash b11a192555ab4d4f054d004e1300cb1f9d7f3b5e8f7708848658ea9051de53d4, and the pool oracle 25e0c7b2b54708da7d48c40d7d6cc9ced97b3ed594e76333bb324092326a6aa3. Each matches a build of the reviewed source. Function-by-function references are in Contracts .
Accounts and transactions
Part What it does Status Source Passkey smart accounts Each user gets a Soroban smart account controlled by a passkey (a secp256r1 key on their device), created at sign-up Live on testnet Server , app Backup passkeys Further passkeys added as signers, each approved by an existing one Live on testnet Server Business accounts One shared smart account per business on OpenZeppelin stellar-accounts 0.8.0, deployed when the business is created; each member approves with their own passkey Live on testnet Service , chain Member roles Admin, operator and viewer, enforced by the account's context rules on chain and by the relayer Live on testnet Roles Transfer allow-list policy Lets operators send USDC from the business account only to the pools; refuses approvals and every other token call Live on testnet CA5B…4WKQSponsored transactions OpenZeppelin Relayer Channels pays network fees, with a BlockFinaX fee account as the fallback; users never hold XLM Live on testnet Relay Signed quotes The pricing service signs each quote (ed25519); the currency pool verifies it Live on testnet Digest
