Endaoment Charity Donations

Donate to 501(c)(3) nonprofits onchain via Endaoment's smart contracts.

Quick Start

Find a Charity

Search by name or EIN:

bash
./scripts/search.sh "27-1661997"         # EIN lookup (GiveDirectly)
./scripts/search.sh "Red Cross"          # Name search

Donate USDC (Base)

bash
./scripts/donate.sh <ein> <amount_usdc>

Example: Donate $5 USDC to GiveDirectly:

bash
./scripts/donate.sh 27-1661997 5

How It Works

The donate script uses Bankr's arbitrary transaction feature to:

Approve USDC to the Endaoment OrgFundFactory
Call deployOrgAndDonate(orgId, amount) which:

Deploys the charity's entity contract on Base (if not already deployed)
Donates the specified USDC amount
