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:

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

Donate USDC (Base)

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

Example: Donate $5 USDC to GiveDirectly:

./scripts/donate.sh 27-1661997 5

How It Works

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

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

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

  • deployOrgAndDonate(bytes32,uint256): 0xdb9e30cc

OrgId Encoding

The EIN (e.g., "11-1666852") is encoded as bytes32:

"11-1666852" → 0x31312d3136363638353200000000000000000000000000000000000000000000

Notes

  • All donations are tax-deductible (US 501(c)(3) orgs)
  • Donations are permissionless — anyone can donate
  • Uses Bankr arbitrary transactions for contract interaction
  • Works on Base; other chains require different addresses
