How it works

Technical flow

EIP-712 Consensus

Each member signs a typed data message. 100% of signatures required — no one is charged without explicit approval.

Atomic Batch Settlement

A single smart contract call transfers USDC between all members. All-or-nothing — no partial settlements.

Gas Sponsored

Paymaster covers gas fees. Flat 0.5% fee in USDC, transparent and verifiable on-chain.

Key differentiators

Why Spliz?

Not custodial

The smart contract executes transfers directly between wallets. Spliz never holds funds.

Not Splitwise + crypto

We don't just calculate — we settle on-chain, trustlessly. One transaction, all balances resolved.

100% consensus

No single member can trigger settlement alone. Every participant must sign before execution.

Built for crypto-native groups

DAOs, hackathon teams, remote contributors — anyone who splits costs and settles in USDC.
