How it works

Three steps. Zero spreadsheets.

01

Create a group

Invite friends with a link, ENS name, or email. They join with a wallet or email — your choice.

02

Add expenses

Snap a receipt — Claude reads it in 2 seconds. Or just type. Splits are equal or exact.

03

Settle anywhere

Mark it paid, send USDC on-chain, or pool funds into a trustless vault. Your call.

Pool funds for trips. Trustlessly.

Group vaults are an audited smart contract on Base. Everyone deposits USDC upfront, anyone claims reimbursements during the trip, and the leftover refunds proportionally on close.

  • No middleman, no custody risk
  • Pro-rata refund on close
  • Per-member claim history
  • "Biggest spender" leaderboard

Install it. Use it on your phone.

SplitChain is a PWA — add it to your home screen and it behaves like a native app. Push notifications when someone adds an expense or pays you back.

  • iOS + Android install
  • Offline-friendly
  • Push notifications
  • Bottom-nav optimized

From the alpha

What early users are saying.

Finally, an expense splitter that gets crypto. Used it on a 6-person ski trip — the vault refund at the end felt like magic.

The receipt scanner is unreal. I take a photo and it just… works. Saved me hours of typing on our Italy trip.

Magic Join sold it for me. My non-crypto friends actually settled on-chain because their first tx was free. They get it now.
