Intent Solver & Filler Bot flyer: Fill the order first, safely.

About this gig

Cross-chain transfers are moving from bridges to intents. A user signs the outcome they want, and fillers compete to deliver it on the destination chain, then settle on the origin chain.

I build fillers and solvers for ERC-7683 order flow and the NEAR Intents solver network. The bot watches orders, prices each one from live feeds, gas and your inventory, simulates the fill, and only sends it within the limits you set. It then tracks settlement and tells you when inventory needs rebalancing.

What you get:

Order-feed listeners for your chosen protocols and routes
Pricing from live feeds, gas and inventory
Pre-fill simulation with size and exposure limits
Settlement tracking, retries and alerts on Telegram
Inventory rebalancing suggestions
A profit-and-loss log and dashboard

I'm building chain-agnostic USDC checkout for WeSelling with NEAR Intents and Circle's CCTP, and I've written about the design on my blog.

Tell me your routes, tokens and how much inventory you can commit.

Use cases

Stablecoin routes

Fill USDC and USDT transfers between L2s, where volume is steady and risk is easy to bound.

Checkout settlement

Settle cross-chain payments for a merchant checkout, the route WeSelling is building with NEAR Intents.

Inventory desk

Put idle balances to work filling orders, with rebalancing alerts when one chain runs low.

What changes

Today

Order flow is moving to intents, and your liquidity isn't in the auction
Filling by hand misses every profitable order
Reorgs, gas spikes and stale prices turn fills into losses
Inventory sits on the wrong chain when orders arrive

After

A filler watching ERC-7683 order feeds or the NEAR Intents solver relay
Quotes priced from live feeds, gas and your inventory
Every fill simulated before sending, with limits on size and exposure
Settlement tracking, rebalancing alerts and a profit-and-loss log

Questions, answered

Do I need my own capital?

Yes. Fillers front funds on the destination chain and get repaid on the origin chain, so you need inventory on the chains you serve. We size it together.

Is it risky?

Fills can lose money through reorgs, failed settlement, gas spikes or stale prices. The bot simulates every fill, caps exposure and stops when something looks wrong. Start on testnet, then go small on mainnet.

Which protocols?

ERC-7683 order flow, such as Across, and the NEAR Intents solver relay. UniswapX-style auctions on request.

Who owns the code and accounts when we finish?

You do. Code goes to your repository, and services run on accounts in your name, so you are never locked to me. I hand over logins, keys and a short guide.

What if my project doesn't fit a package?

Send a message describing what you need. I reply with a custom offer priced to the actual scope, often after a short call.

The thinking behind it

Get Paid in Dollars with a Stablecoin CheckoutInternational customers struggle to pay African businesses, and cards and wires eat the margin. How a USDC checkout sits next to Paystack, Flutterwave and Stripe, confirms payment on-chain and keeps clean records.
