KMS) where the signing key is unknown.\n\n```typescript\nimport {\n createChargeDigest,\n signDigest,\n CreateChargeDigestInput,\n ECDSASignature,\n} from \"@diagonal-finance/crypto\";\n\nconst chargeDigestInput: CreateChargeDigestInput = {\n id: \"charge_17e8e79988359da2be9678f0b9936671c2031d0724abab99\",\n source_address: \"0x4632Ea8C867aaB1c93bf4B21b8FeD4958d111Cc0\",\n token_address: \"0x07865c6e87b9f70255377e024ace6630c1eaa37f\",\n token_amount: \"10000000\",\n organization_address: \"0xf78eA64621d8e2E7fCafdbc7cEd53b20edA526a0\",\n chain_id: 1,\n};\n\nconst chargeDigest: string = createChargeDigest(chargeDigestInput);\n\nconst privateKey = process.env.SIGNER_PRIVATE_KEY;\n\nconst signature: ECDSASignature = signDigest(chargeDigest, privateKey);\n```\n\n## šŸ›  Development\n\nClone this repository and install the dependencies:\n\n```bash\ngit clone https://github.com/diagonal-finance/crypto.git\ncd crypto && npm i\n```\n\n### šŸ“œ Usage\n\n```bash\nnpm run lint # Syntax check with ESLint (yarn lint:fix to fix errors).\nnpm run format # Syntax check with Prettier (yarn prettier:fix to fix errors).\nnpm test # Run tests (with common coverage).\nnpm run build # Create a JS build.\nnpm run publish # Publish a package on npm.\n```\n","readmeFilename":"README.md"}
