Summary: Splits is an onchain financial-operations platform that pairs open-source payment primitives with a newer banking-and-treasury layer for builders. Its official site, docs, and GitHub materials show two related surfaces: zero-fee payment contracts for splitting, waterfalling, and swapping onchain revenue, and a Teams platform built around ERC-4337 smart accounts, subaccounts, treasury workflows, accounting, invoicing, bank transfers, and crosschain asset management.
What it does:
Provides open-source payment contracts that let teams distribute onchain revenue by percentage, priority ordering, or automatic token conversion
Runs a contract-based system where funds are received into contracts, distributed by callable functions, and withdrawn from shared accounting layers like SplitWarehouse or SplitMain
Offers a developer SDK, contract docs, and public repos for integrating Splits primitives into apps and workflows
Builds crosschain multi-signature smart accounts with passkey and EOA signer support, ERC-1271 verification, modules, and ERC-4337-style account abstraction
Positions Splits Teams as a broader financial-ops layer for treasury management, subaccounts, expenses, payroll, bank transfers, accounting exports, and automated stablecoin conversion for builders and small teams
Key claims:
The official site describes Splits as “banking for onchain builders” and frames the platform around shared wallets, treasury management, accounting, bank transfers, automations, and invoicing
The docs describe Splits as open-source, audited smart contracts that run exactly at gas cost, charge no protocol fees, and are designed as a hyperstructure that runs without trusted third parties
The docs and GitHub org show Splits is multichain, with deployed payment primitives plus newer smart-account infrastructure rather than only a single royalty-split contract
The public GitHub profile says the contracts are audited, zero-fee, deployed on 13+ chains, and have distributed $250M+ while the Teams platform supports full smart-account features on selected networks and bridging to 70+ EVM chains via Relay
The smart-vaults repository materials make clear that Splits is also building ERC-4337-compatible multi-chain multi-sig infrastructure with passkeys, Merkleized User Operations, and light UserOp signing flows
The strongest primary-source signal is that the project now spans both public-good payment legos and an operational treasury platform, so cataloging it only as “revenue splits” would understate the scope
Whitepaper: No classic standalone whitepaper or litepaper was found during this pass. The strongest primary materials were the official website, docs, GitHub org/profile, contracts monorepo, and smart-vault documentation; see ../whitepapers/splits-primary-sources-2026-04-26.md.
