Cross-Chain Infrastructure
for Every Blockchain Type

Move assets between Bitcoin, EVM, Solana, TON, and privacy chains. No custodians. Threshold signatures where the private key never exists. Formally proven security.

What Bridgeless Does

Bridge assets between Bitcoin, Ethereum, Solana, TON, and privacy chains through one protocol with its own settlement layer.

settlement

Own L1 for Settlement

Every deposit and withdrawal is recorded on a dedicated Cosmos SDK chain with Tendermint BFT consensus. The bridge state lives on its own ledger, not on a third-party chain.

signing

No Single Point of Failure

The private key never exists as a whole. Validators each hold a share and co-sign withdrawals using threshold cryptography. The network tolerates up to 1/3 malicious validators.

custody

Your Keys, Your Chains

Funds stay in chain-native contracts or TSS-controlled addresses. Deposits are verified directly against the source chain. If the bridge goes down, pending transactions are queued and settled on recovery.

How It's Different

Most bridges rely on a company or a fixed set of signers. Bridgeless uses threshold cryptography where the private key never exists as a whole.
