Search by name or EIN:
bash
./scripts/search.sh "27-1661997"         # EIN lookup (GiveDirectly)

./scripts/search.sh "Red Cross"          # 按名称搜索

Donate USDC (Base)

捐赠USDC（Base链）

bash
./scripts/donate.sh <ein> <amount_usdc>
Example: Donate $5 USDC to GiveDirectly:
bash
./scripts/donate.sh 27-1661997 5
bash
./scripts/donate.sh <ein> <amount_usdc>
示例：向GiveDirectly捐赠5美元等值的USDC：
bash
./scripts/donate.sh 27-1661997 5

How It Works

工作原理

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
捐赠脚本调用Bankr的任意交易功能完成以下操作：
  1. 向Endaoment OrgFundFactory授权USDC额度
  2. 调用
    deployOrgAndDonate(orgId, amount)
    方法，该方法会：
    • 如果该慈善机构的实体合约尚未在Base链部署，则先完成部署
    • 捐赠指定数量的USDC

OrgId Encoding

OrgId Encoding

The EIN (e.g., "11-1666852") is encoded as bytes32:
"11-1666852" → 0x31312d3136363638353200000000000000000000000000000000000000000000
EIN（例如"11-1666852"）会被编码为bytes32格式：
"11-1666852" → 0x31312d3136363638353200000000000000000000000000000000000000000000

Notes

注意事项

  • 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
  • 所有捐款均可抵税（针对美国501(c)(3)组织）
  • 捐赠无需许可，任何人都可以进行捐赠
  • 使用Bankr任意交易功能完成合约交互
  • 当前仅支持Base链，其他链需要使用对应的不同合约地址
