Last Updated: 2026-02-12
Purpose: Reusable project descriptions for listings, Ledger, Chainlist, CoinGecko, outreach, and documentation.
Short (1–2 sentences)
For: Forms, badges, meta tags, character-limited fields.
Option A (technical):
Defi Oracle Meta Mainnet (Chain ID 138) is an EVM-compatible blockchain built on Hyperledger Besu with QBFT consensus, offering ~2s block time, native oracle integration, and CCIP cross-chain bridges.
Option B (use-case):
Defi Oracle Meta Mainnet is an enterprise-grade EVM chain (Chain ID 138) with compliant stablecoins, cross-chain bridges (CCIP), and native oracle support for institutional DeFi.
Option C (minimal):
Production EVM chain (Chain ID 138) on Hyperledger Besu with QBFT, CCIP bridges, and Blockscout explorer.
Medium (one paragraph)
For: Ledger submission, Chainlist, CoinGecko chain description, listing blurbs.
DeFi Oracle Meta Mainnet (Chain ID 138) is an enterprise-grade, EVM-compatible blockchain built on Hyperledger Besu with QBFT consensus. It features ~2-second block time, native oracle integration, Chainlink CCIP cross-chain bridges to Ethereum Mainnet and other EVM chains, and compliant stablecoins (cUSDT, cUSDC, cEURC) for institutional DeFi applications. The network is production-ready with public RPC endpoints, a Blockscout block explorer, and full MetaMask and Chainlist support.
Long (full description)
For: README, submission packages, detailed outreach, documentation.
DeFi Oracle Meta Mainnet (Chain ID 138) is a production-ready, EVM-compatible blockchain built on Hyperledger Besu with QBFT consensus. It provides immediate finality with approximately 2-second block time and is designed for institutional DeFi with native oracle integration, cross-chain bridges, and compliant assets.
Network: Chain ID 138 (0x8a), native currency ETH (18 decimals), standard EVM derivation (SLIP-44: 60). EIP-155 and EIP-1559 supported.
Infrastructure: Tiered architecture (validators, sentries, RPC nodes), public RPC endpoints (HTTPS and WebSocket), and Blockscout block explorer at https://explorer.d-bis.org. Information and docs: https://d-bis.org.
Cross-chain: Full Chainlink CCIP implementation (CCIP Router, CCIPWETH9Bridge, CCIPWETH10Bridge) for cross-chain transfers with Ethereum Mainnet and other supported chains. LINK-based fees; relay and monitoring tooling deployed.
Assets: Compliant stablecoins (cUSDT, cUSDC, cEURC), WETH9/WETH10, LINK, and a token registry with compliance controls. Oracle price feeds and keeper infrastructure for institutional use.
Ecosystem: MetaMask integration (custom network and Chainlist), thirdweb bridge support, token aggregation and market-data APIs, and deployment automation. Listed on Chainlist (chainlist.org/chain/138).
