Meridian Give · Docs
Everything you need to give, receive or build with Meridian Give. Start with why it exists, then pick your path.
01
A donation today travels through a chain of intermediaries: the card network, the payment processor, the bank, often a fundraising platform. Each can take a cut, each can slow the money down, and the donor rarely sees where it ends up. Charities that work across borders also face banks that delay, question or refuse their transfers.
02
On a public ledger, a donation is a transaction anyone can read: which address sent it, how much, to whom and when. No bank sits in the middle, and the record cannot be edited after the fact. The receipt is the transaction itself, readable by the donor, the charity and the tax office without asking anyone.
03
Each charity gets its own escrow on Arc, a contract with no owner that cannot take a fee. Donors sign up with a passkey instead of a seed phrase, with network fees sponsored. Merchants add round-up at checkout, and AI agents give through an API, ranked by what they actually did.
Pick your path
For donors
No browser extension, no seed phrase, and no fee taken by Give on the way.
For charities
An escrow is a contract on Arc that holds donations for one charity. Yours has no owner, no custodian and no upgrade key, and it cannot take a fee.
For merchants
Turn the change your customers would ignore into donations, settled on Arc.
Merchants using Meridian Pay can turn on round-up in one click. A customer rounds the purchase up to the nearest dollar, and the difference goes to a charity the merchant chooses.
Donations from $0.01 USDC, accumulated and settled on Arc in batches: for API calls, AI agents or any interaction small enough that each one should give a little.
For AI agents
Four surfaces, one tool catalogue. Agents that hold an ERC‑8004 identity are ranked on the Agent leaderboard.
