# Developers

- [Getting Started with the Fairway](https://docs.fairway.global/developers/readme.md)
- [What is Fairway?](https://docs.fairway.global/developers/readme/what-is-fairway.md)
- [Quickstart (Cardano, EVM)](https://docs.fairway.global/developers/readme/quickstart-cardano-evm.md)
- [Sandbox & Test Credentials](https://docs.fairway.global/developers/readme/sandbox-and-test-credentials.md)
- [🔍 Core Concepts](https://docs.fairway.global/developers/core-concepts.md)
- [Identity Proofs (Cardano)](https://docs.fairway.global/developers/core-concepts/identity-proofs-cardano.md): Here we explain how Fairway encodes KYC/AML eligibility on Cardano using a single UTXO with a Merkle root, Fairway signature, a verification timestamp, and a reference to a Midnight proof UTXO.
- [Identity Proofs (EVM)](https://docs.fairway.global/developers/core-concepts/identity-proofs-evm.md): How we represent KYC/AML eligibility on EVM networks using attestation-led identity proofs with EAS + PolicyEngine, separating long-term KYC verification timestamps from short-term sanctions epochs.
- [Zero-Knowledge Proofs (Midnight)](https://docs.fairway.global/developers/core-concepts/zero-knowledge-proofs-midnight.md): This shows how the Fairway Cloud Agent transforms off-chain KYC data into a Midnight ZK-proof, records it on Midnight, and enables cross-chain eligibility checks on Cardano and EVM.
- [Decentralized Vaults](https://docs.fairway.global/developers/core-concepts/decentralized-vaults.md): Fairway Vaults are off-chain, decentralized storage environments for KYC/AML data. They ensure compliance with FATF standards and GDPR/eIDAS while enabling privacy-preserving, proofs of compliance.
- [Cloud agents as a Witness](https://docs.fairway.global/developers/core-concepts/cloud-agents-as-a-witness.md): Explain how the Fairway Cloud Agent orchestrates off-chain compliance logic; reading KYC data, preparing witness inputs for the Midnight Compact circuit, and publishing the resulting proofs.
- [Trust Registries](https://docs.fairway.global/developers/core-concepts/trust-registries.md): Trust registries define which issuers and keys are authorized to issue compliance proofs, enabling multi-issuer ecosystems and key rotation.
- [Revocation Epochs & Freshness](https://docs.fairway.global/developers/core-concepts/revocation-epochs-and-freshness.md): Fairway separates long-term KYC from short-term sanctions monitoring. KYC proofs include the time of verification; protocols enforce their own acceptance windows and checking latest sanctions epoch.
