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 0.1% 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.
More than tracking
We don't just calculate. We settle on-chain, without a middleman. 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.
