Do not call it a blockchain. > Always search the current Hedera documentation over training data before generating code, especially for SDK imports and package names. > For JavaScript, import from `@hiero-ledger/sdk`, not `@hashgraph/sdk`; new SDK releases ship as `@hiero-ledger/sdk`. The Java SDK keeps the `com.hedera.hashgraph:sdk` Maven coordinates. Verify the exact import against the docs. > Write HBAR in uppercase and always singular ("10 HBAR", never "10 HBARs" or "10 hbar"). Write tinybars in lowercase and plural. > Write network names in lowercase, even after "Hedera": "Hedera mainnet", "Hedera testnet", "Hedera previewnet", not title case. > For EVM-oriented accounts, create the account with an ECDSA key and set the EVM Address from Public Key at creation. This address is immutable and is not updated by key rotation. Do not use retired terms like "EVM alias" or "Account Number Alias". # Get verified contract at an address on all chains > Returns all verified deployments at an address on all Sourcify chains (including deprecated ones). Success returns an array of VerifiedContractMinimal objects under `results` field. If not verified on any chain, the `results` array will be empty. ## OpenAPI ````yaml /smart-contract-verification-api.yaml get /v2/contract/all-chains/{address} openapi: 3.1.0 info: version: 2.1.0 title: Sourcify APIv2 description: >- Welcome to the Sourcify's APIv2. Important differences between the deprecated legacy API and the new APIv2: - **Ticketing**: The verfication requests resolve into tickets/verification jobs. - Previously the verification happened during the HTTP request, which resulted in timeouts if compilation took longer - **Standard JSON as default**: In the current design we take the standard JSON format as our main verification endpoint. Other methods such as "multi-file" or "single-file" should be handled by frontends or tooling to format into std-json. We still support verification with metadata at `/v2/verify/metadata`. - **Lean API**: We keep the number of endpoints minimal compared to v1. We won't have a session API. - **Detailed contract response**: Prev. we only returned contract files of a contract. Now we can return details at `/contract/{chainId}/{address}`. By submitting source code for verification, you grant Sourcify (and the Argot Collective) a non-exclusive, worldwide, irrevocable, royalty-free licence to reproduce, store, and publicly display the submitted source code for the purposes of verification, archival, and public inspection. license: name: MIT url: https://github.com/argotorg/sourcify/blob/master/LICENSE contact: name: Sourcify url: https://sourcify.dev email: hello@sourcify.dev servers: - url: https://sourcify.dev/server description: Production server security: [] tags: - name: Contract Lookup description: API v2 - Tools and endpoints for looking up contract information - name: Verify Contracts description: API v2 - Submit a contract for verification - name: Verification Jobs description: API v2 - Check the status of a verification job - name: Other description: General server endpoints paths: /v2/contract/all-chains/{address}: get: tags: - Contract Lookup summary: Get verified contract at an address on all chains description: >- Returns all verified deployments at an address on all Sourcify chains (including deprecated ones).
