Find a contract deployment

portal_evm_get_contract_deployment

Read-only

Find the deployment transaction, deployer, and deployment block for any EVM contract address within a specified block or time window.

Instructions

Locate the create trace and parent transaction that deployed a specific EVM contract address within a bounded window.

COMMON USER ASKS:

Find BAYC deployment
Find recent deployment
Find deployment from known range

FIRST CHOICE FOR:

who deployed this EVM contract
when was this contract deployed
what deployment transaction created this contract

WHEN TO USE:

You need the deployer, deployment block, deployment timestamp, or deployment transaction for an EVM contract.
You can provide a starting block/time window, a contract address, or a supported well-known contract alias such as BAYC/Bored Apes.
You want a deployment lookup instead of general contract activity.

DON'T USE:

You need all activity for a contract after deployment.
The contract is old and no block/time hint is available; provide from_block or from_timestamp first.

EXAMPLES:

Find BAYC deployment: {"network":"ethereum-mainnet","contract":"bored apes","from_block":12000000,"to_block":13000000,"scan_order":"earliest"}
Find recent deployment: {"network":"base-mainnet","contract_address":"0xabc...","search_depth_blocks":100000}
Find deployment from known range: {"network":"ethereum-mainnet","contract_address":"0xabc...","from_block":17000000,"to_block":17100000,"scan_order":"earliest"}

TDQS

A4.4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds meaningful behavioral context beyond that: the search is bounded to a window, it returns the create trace and parent transaction, and it notes that old contracts without a block/time hint are not suitable. This is useful context without contradicting the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is longer than average but is well-structured into clear sections (COMMON USER ASKS, FIRST CHOICE FOR, WHEN TO USE, DON'T USE, EXAMPLES) and front-loads the core purpose in the first sentence. Some redundancy exists between 'COMMON USER ASKS' and 'FIRST CHOICE FOR,' so it is not maximally concise, but every section contributes useful guidance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (11 parameters, multiple ways to specify the contract/range), the description is complete: it covers use cases, exclusions, parameter semantics, examples, and the critical constraint about providing block/time hints for older contracts. The output schema exists, so not describing return values is acceptable. An agent can correctly select and invoke this tool with the information provided.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, providing a baseline of 3. The description adds real value above the schema by explaining parameter relationships and usage patterns, such as using from_block for older contracts, search_depth_blocks when no explicit range is given, and contract aliases like 'bored apes'. The three examples illustrate valid, concrete parameter combinations that the schema alone does not convey.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Locate the create trace and parent transaction that deployed a specific EVM contract address within a bounded window.' This clearly distinguishes it from sibling tools like contract activity or transaction queries, and the 'DON'T USE' section reinforces that it is for deployment lookup rather than general activity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'WHEN TO USE' and 'DON'T USE' sections give explicit conditions and exclusions, such as not using it for all post-deployment activity and requiring from_block/from_timestamp for older contracts. It clearly describes the deployment-lookup use case but does not name a specific sibling alternative (e.g., portal_evm_get_contract_activity) by tool name, so it falls just short of fully explicit alternative routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
