A comprehensive overview of Setu's cross-chain bridge infrastructure.
Setu (सेतु – Sanskrit for "Bridge") is a decentralized stablecoin bridge protocol designed to facilitate secure and efficient cross-chain transfers between EVM and non-EVM blockchains. Built on Internet Computer Protocol (ICP), Setu leverages threshold cryptography within decentralized canisters, eliminating the need for centralized relayers or custody.
Non-custodial design with threshold signatures and decentralized canisters
Intuitive interface with minimal steps for cross-chain transfers
Low fee of 0.3% with fast processing and minimal confirmation times
Setu is composed of specialized components working in concert to enable secure cross-chain transfers:
Interface for users to bridge funds and manage liquidity.
Listens to events on source chains, verifies transactions, and coordinates signatures.
Decentralized signers for each chain family (Solana, Stellar, EVM).
Chain-specific contracts to lock assets and emit events.
Setu uses a secure and efficient process to transfer stablecoins across chains:
User sends stablecoins to the Lock Contract on the source chain
Indexer Canister on ICP detects the lock event
Threshold signatures created for destination chain transaction
Transaction executed on destination chain, transferring tokens to the user
