BRDG is a cross-chain bridge aggregator. You send one quote request, BRDG asks every bridge that serves the route, ranks the answers by how much arrives in the destination wallet, and returns the unsigned transaction for the one you pick. Your users sign from their own wallets. BRDG never holds funds or keys.
  • 38 venues: intent bridges, liquidity pools, canonical bridges, exchange desks and other aggregators. See Venues.
  • 73 chains, including EVM chains, Solana, Bitcoin and other UTXO chains, Tron, Move chains and Cosmos. See Chains.
  • Ranked on what arrives. Quotes are compared on net output in the token’s own units, after every fee. No price feed decides the winner.
  • Free unless BRDG saved your user money. There is no platform fee unless the chosen route beat the alternatives by more than 10 bps, and the fee never exceeds $10 a transfer. See Fees.
  • No API key and no account. Quote, build and submit are open, subject to rate limits.
