Why Cofferdam

Built better than
current payday technology.

Zero fees on you. Ever.

You receive the full amount your company sends. No transaction fee, no FX spread, no held wires. Cash out to your local rail when you're ready.

Sybil-resistant identity

Verified with your passport via Self.xyz. One person, one wallet. No fraud, no fake accounts, no duplicate payrolls — yours or anyone else's.

Self-custodial by default

Your keys, your money. No bank can freeze it. No platform can lose it. Sign in with Face ID — no seed phrase to write down.

End-to-end encrypted

Conversations with your employer, attestations, documents — all encrypted. Your phone is the only place plaintext lives.

Local off-ramp

Cash out to GCash, Pix, UPI, Mobile Money. Cheapest provider per country, transparent on the spread.

The math: vs. Western Union: 5–7% fee per transfer. vs. SWIFT: 3-day held wires. Cofferdam: 0% to you, settles in seconds.

Under the hood

Three primitives.
One ceremony.

From contract signature to payment release — here's the whole flow, on-chain and verifiable.

Worker

Contract

Company

Contracts

Sign once. Settle on-chain.

Worker and company both sign a typed contract on ZKSync Era. The contract holds the terms — amount, schedule, witness, conditions. Payment releases trigger automatically when conditions are met.

Worker

E2E

Company

Messaging

Conversations stay private.

Worker and company exchange documents, attestations, and payment notes through an end-to-end encrypted channel keyed by their passkeys. Even Cofferdam can't read it.

On-site

Witness

Paid

Proof-of-presence

Witnesses release payments.

Companies set a witness — a foreman's signature, a GPS coordinate, a signed delivery doc. When the witness confirms the condition, the contract releases payment. No invoicing, no chasing.
