Bridg is a cross-chain bridge aggregator. One request prices a transfer across every bridge that serves the route, ranks the results by the amount that lands in the destination wallet, and returns the unsigned transaction for the best one. Your users sign from their own wallets. Bridg never holds funds or keys.
  • 36 venues: intent bridges, liquidity pools, canonical rails, exchange desks and other aggregators.
  • 73 chains across EVM, Solana, Bitcoin-family, Tron, Move, Cosmos and more.
  • Ranking is on net output in the asset’s own units, after every fee. No price feed decides a winner.
  • No platform fee unless the aggregation saved your user more than 10 bps. Never more than $10.
  • No API key and no account to quote, build or submit.
