Compliant DeFi on Cardano
Compliance oracle for permissioned DeFi pools. Connect your wallet, verify your identity, and borrow from regulated lending pools — all on-chain.
How It Works
Three steps to borrow from a regulated, permissioned DeFi pool on Cardano.
Connect Wallet
Link your Cardano wallet (Eternl, Lace) to access permissioned DeFi pools on the Preview testnet.
Verify Compliance
Complete KYC verification through Zyphe. The Oracle issues a signed compliance token attesting your identity.
Transact On-Chain
Submit borrow transactions with the compliance token as redeemer. The Aiken validator verifies the oracle signature on-chain.
What is a Compliance Oracle?
A compliance oracle is an off-chain service that verifies a borrower's KYC status and issues a signed compliance token. This token is submitted on-chain as a redeemer, where the Aiken smart contract verifies the oracle's Ed25519 signature and checks the oracle's key hash against the pool's whitelist.
System Architecture
A three-layer stack for compliant DeFi on Cardano.
API Server
Express.js server signs compliance tokens with Ed25519 keys. KYC verification via Zyphe webhooks.
Aiken Validators
On-chain Ed25519 signature verification and permissioned oracle whitelist management.
CBOR Compatible
Perfect serialization match between TypeScript and Aiken for deterministic compliance token verification.
