USDC cash officer
Cash thatcomes backon time.
Keep enough USDC ready for payroll and agent spend. Ebbryn parks the rest in IXS vaults, then schedules it back before each payout. You sign every move, including the withdrawal.
SERV plans. Code checks. IXS builds. You sign.
Testnet. IXS vaults need verification on mainnet.
Idle cash
Money waiting for payday earns nothing.
USDC sitting idle doesn't earn yield on its own. Put in your own numbers.

Payroll teams
Pay contractors in USDC? Your float can work until payday.
You fund payroll days or weeks before it goes out. Ebbryn keeps each pay run covered and parks only the cash you won't need before then.
- Covers every payroll date
- Keeps the buffer you choose
- Parks only what you won't need
Agent operators
Keep every agent funded. Put the rest to work.
Agents that pay for APIs need topped-up wallets every day. Ebbryn plans the fleet's daily spend as one schedule, so the buffer is sized in days instead of guesses.
- Daily top-ups covered
- Buffer in days, not guesses
- One plan for the whole fleet

Why code checks the model
We asked a model to plan payroll cash. It counted payroll twice.
A real SERV answer from our testing, run through the same eight checks every Ebbryn plan goes through. It never reached a wallet.
- Keep ready
- 8,450
- Park
- 11,550
- 01
Keep $450 liquid for three days of agent spend at $150 per day, plus $8,000 for the Oct 1 payroll, so payroll is covered without relying on the vault claim arriving.
- 02
Park $11,550, which is below the 60% maximum of $12,000.
- 03
Request redemption of $8,000 on Sep 28 so it can land Sep 30, one day before payroll.

How it works
Three steps. You stay in control of every one.
- 01
Your payouts
Add what's coming up: payroll dates, agent top-ups, anything with a date and an amount. Then write your cash rules in plain English.
- 02
SERV plans, code checks
SERV Reasoning weighs your rules and proposes how much stays ready and how much goes to work. Eight checks run on every plan before you see it.
- 03
You sign
IXS builds each transaction. You see the contract and the amount, and nothing moves until you sign it in your own wallet.
What the checks guarantee, on every plan:
- Every payout is funded exactly once
- Nothing goes into a vault that isn't taking deposits
- Withdrawals are timed to land a day early
- Your hard limits beat anything written in the rules
Built on
Two layers doing real work.
OpenServSERV Reasoning
Plans every split. Kronos and Multipath keep a small model on your rules, and Shadow Agent checks each draft before Ebbryn's own checks run.
openserv.aiRWA vaults
Holds the parked cash. Ebbryn reads live vault status from IXS and gets every deposit transaction built by the IXS MCP server.

Where the money goes
RWA vaults from IXS.
Read from IXS. Ebbryn only parks money in a vault that is open for deposits right now.
