Built on Base · USDC

Invoice anywhere.
Get paid in stablecoins.

Linedger is non-custodial invoicing for freelancers who get paid in USDC directly to their wallet — no fiat off-ramp, no bank rail, no middleman holding your money on the way to you.

Launch appHow it works
Direct to your wallet
No off-ramp, no bank rail, no intermediary holding your funds. Clients pay your USDC address on Base — you hold the keys the whole time.
Paid automatically, detected on-chain
Activate an invoice and Linedger watches the chain for a matching transfer. No manual confirmation, no waiting on someone else to mark it paid.
A receipt that can't be disputed
Every payment stores its transaction hash — a permanent, verifiable record of exactly when and how you got paid.
How it works
01
Create the invoice
Client name, amount in USDC, and the wallet address you want paid to.
02
Share the payment link
Send your client a manifest they can open — the amount, the address, nothing else required.
03
Watch it clear
The moment the transfer lands on-chain, your invoice flips to Paid with the tx hash attached.
Currently live on Base Sepolia testnetwhile the payment watcher gets battle-tested — don't send real funds yet. What this doesn't do: any fiat off-ramp or local bank payout. Direct-to-wallet only, by design.
Linedger never takes custody of your funds — invoices point straight at your own wallet address, and the chain is the source of truth for whether you got paid.
