|
||
|
||
**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).
