RAIL20 unlocks

Private on-chain payments.

Private B20 payments on Base.

The RAIL20 thesis

RAIL20 decentralizes privacy for on-chain value the same way Base scaled transactions.

Every transfer, balance, and swap on public chains is exposed by default - handing your financial footprint to anyone watching the mempool.

The RAIL20 thesis: private, self-custodial payments will be the backbone of real on-chain finance - unlocking a vast white space of B20 use cases without sacrificing the openness of Base.

Shield, send, swap, and bridge B20 tokens with zero-knowledge privacy. Your balance stays invisible, your transfers leave no trail. No sign-ups, no KYC, no custody.

SHIELD

Move tokens into the private pool in one transaction. On-chain balance becomes invisible.

SEND

Private transfers to any shielded address. No amounts, no trail.

SWAP

Swap into private tokens through a one-time burner wallet - no link to your wallet.

BRIDGE

Move value privately across chains - Base, Arbitrum, and BNB Chain.
