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.

L1What Bridgeless Does
Bridge assets between Bitcoin, Ethereum, Solana, TON, and privacy chains through one protocol with its own settlement layer.
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.

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.

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.

Connected Blockchains
UTXO chains, smart contract platforms, and privacy networks, all connected through one protocol.

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.

|---|---|---|---|
| Key management | Single custodian | N-of-M known operators | T-of-N threshold (no full key exists) |
| Bitcoin support | Wrapped token (e.g. WBTC) | Wrapped via federation | Native UTXO via TSS-controlled address |
| Privacy chains | Not supported | Not supported | Native integration (Zano burn_asset) |
| Settlement | Off-chain or L2 | Off-chain | Dedicated L1 (own Cosmos SDK chain) |
| Fault tolerance | Not supported | Manual intervention | Tolerates up to 1/3 malicious validators |
