# Mezo > Mezo is Bitcoin's economic layer — a Cosmos SDK-based appchain with full EVM compatibility, built by Thesis (creators of tBTC, Fold, and Taho). Bitcoiners can borrow, lend, spend, save, and earn yield without selling their BTC: BTC is the native gas token, tBTC provides reliable bridging, and MUSD is a Bitcoin-backed stablecoin pegged 1:1 to the U.S. dollar. The chain runs the mezod reference client on CometBFT consensus with a dual-staking model. This llms.txt was generated by the API Evangelist enrichment pipeline from the provider's public developer docs and repositories. Mezo publishes no OpenAPI; its programmatic surface is Ethereum JSON-RPC (EVM), Cosmos REST/gRPC + CometBFT RPC, and a Blockscout explorer API. ## Networks - Mezo Mainnet: EVM chain ID 31612 (cosmos: mezo-mainnet), currency BTC (18 decimals), explorer https://explorer.mezo.org - Mezo Testnet: EVM chain ID 31611 (cosmos: mezo-testnet), EVM RPC https://rpc.test.mezo.org, explorer https://explorer.test.mezo.org ## Docs - Documentation: https://mezo.org/docs - Developer docs: https://mezo.org/docs/developers - Getting started: https://mezo.org/docs/developers/getting-started/ - Configure environment (Hardhat/Foundry, RPC, chain IDs): https://mezo.org/docs/developers/getting-started/configure-environment/ - Chains configuration guide: https://mezo.org/docs/developers/chains/ - mezod chain client guide: https://mezo.org/docs/developers/getting-started/mezod/ - MUSD payments over x402: https://mezo.org/docs/developers/getting-started/musd-payments-x402/ - FAQ: https://mezo.org/faq ## APIs - Mezo EVM JSON-RPC (testnet): https://rpc.test.mezo.org - Mezo CometBFT / Cosmos RPC (mainnet): https://rpc.mezo.org - Block explorer (Blockscout): https://explorer.mezo.org ## Repositories - GitHub organization: https://github.com/mezo-org - mezod (reference client): https://github.com/mezo-org/mezod - musd (MUSD contracts + dapp): https://github.com/mezo-org/musd - chains (Viem config): https://github.com/mezo-org/chains - documentation: https://github.com/mezo-org/documentation - validator-kit: https://github.com/mezo-org/validator-kit - audits: https://github.com/mezo-org/audits ## Packages - @mezo-org/chains (npm): https://www.npmjs.com/package/@mezo-org/chains - mezo CLI (Homebrew/Scoop/Chocolatey/AUR/APT): brew install mezo-org/tap/mezo ## Company - Website: https://mezo.org - Blog: https://mezo.org/blog - Discord: https://discord.com/invite/mezo - Status: https://monitoring.mezo.org/grafana/public-dashboards/ce8d1e04916244b0908cb967b8530f5f - Terms of Service: https://mezo.org/legal/terms - Privacy Policy: https://mezo.org/legal/privacy - Security: https://mezo.org/.well-known/security.txt
