Staking - c8ntinuum Docs

Overview

The Staking precompile provides a Solidity interface to the Cosmos SDK x/staking module. Smart contracts can create validators, manage delegations, and query staking state. Precompile Address: 0x0000000000000000000000000000000000000800

Gas Costs

Method Type	Gas Cost
Transactions	`2000 + (30 x bytes of input)`
Queries	`1000 + (3 x bytes of input)`

Transaction Methods

Method	Description
`createValidator`	Create a new validator with description, commission, and self-delegation
`editValidator`	Update validator description and commission
`delegate`	Delegate tokens to a validator
`undelegate`	Undelegate tokens (begins unbonding period)
`redelegate`	Move delegation from one validator to another
`cancelUnbondingDelegation`	Cancel an in-progress unbonding

Query Methods

Method	Description
`delegation`	Get delegation details for a delegator-validator pair
`unbondingDelegation`	Get unbonding delegation details
`validator`	Get validator information
`validators`	List all validators with pagination
`redelegations`	Get redelegation entries

Example

// Pseudocode: import IStaking and Coin from the canonical interface.
IStaking constant staking = IStaking(0x0000000000000000000000000000000000000800);

// Delegate 1000 tokens to a validator
staking.delegate(msg.sender, "c8valoper1...", 1000000000);

// Query delegation
(uint256 shares, Coin memory balance) = staking.delegation(msg.sender, "c8valoper1...");

Cosmos module precompiles use the chain’s native decimal precision. c8ntinuum’s base denom is ctm with exponent 18; check each precompile’s expected amount format before interacting with it.
