30+ supported chains
Guardian network validation
Token and NFT bridging

LayerZero

Ultra-light node protocol for omnichain interoperability. Low-cost messaging with configurable security via oracles and relayers.

Omnichain messaging
Configurable security model
Low-latency transfers

Axelar

Universal overlay network connecting all blockchains. Proof-of-stake security with General Message Passing for complex cross-chain logic.

PoS-validated security
General Message Passing
EVM and Cosmos support

DeFi Protocol Connectors

Access the most trusted DeFi protocols through a unified API. Swap, lend, stake, and optimize yield without managing multiple integrations.

Uniswap V3

DEX

Concentrated liquidity DEX with optimal price execution. Multi-hop routing across token pairs with slippage protection.

Aave V3

Lending

Decentralized lending and borrowing protocol. Supply assets to earn yield or borrow against collateral with flash loan support.

Curve Finance

Stableswap

Optimized AMM for stablecoin and pegged asset swaps. Minimal slippage with deep liquidity pools and gauge-boosted yields.

Lido

Liquid Staking

Liquid staking for ETH and other PoS assets. Earn staking rewards while maintaining liquidity through stETH derivative tokens.

API Endpoints

A unified REST API for cross-chain bridging and DeFi operations. All endpoints require Bearer token authentication.

Cross-Chain Bridging

Discover chains, get quotes, and initiate bridge transfers across networks.

GET /api/v1/crosschain/chains

POST /api/v1/crosschain/bridge/quote

POST /api/v1/crosschain/bridge/initiate

DeFi Operations

Swap tokens, track portfolios, and discover the best yield opportunities.

POST /api/v1/defi/swap/quote

GET /api/v1/defi/portfolio

GET /api/v1/defi/yield/best

Example: Get Bridge Quote

// Request a bridge quote across providers
const response = await fetch('https://api.finaegis.com/api/v1/crosschain/bridge/quote', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_TOKEN',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    source_chain: 'ethereum',
    destination_chain: 'polygon',
    token: 'USDC',
    amount: '1000.00'
  })
});

const { quotes } = await response.json();
// quotes array sorted by best fee, includes Wormhole, LayerZero, Axelar options
console.log('Best route:', quotes[0].provider);
console.log('Fee:', quotes[0].fee);
console.log('ETA:', quotes[0].estimated_time);
