Struct NeoburgerContract

pub struct NeoburgerContract<'a, P: JsonRpcProvider> { /* private fields */ }

NeoburgerNeo contract interface for Neo N3

NeoburgerNeo (bNEO) is a wrapped NEO token that allows users to earn GAS while using their NEO in DeFi. This contract interface provides methods to interact with the NeoburgerNeo smart contract.

pub fn new(provider: Option<&'a RpcClient<P>>) -> Self

Creates a new NeoburgerContract instance with the default contract hash

Arguments

• provider - An optional reference to an RPC client

Returns

A new NeoburgerContract instance

pub fn with_script_hash( script_hash: ScriptHash, provider: Option<&'a RpcClient<P>>, ) -> Self

Creates a new NeoburgerContract instance with a custom script hash

Arguments

• script_hash - The script hash of the NeoburgerNeo contract
• provider - An optional reference to an RPC client

Returns

A new NeoburgerContract instance

pub async fn wrap( &self, amount: i64, account: &Account, ) -> Result<TransactionBuilder<'_, P>, ContractError>

Wraps NEO to bNEO

Arguments

• amount - The amount of NEO to wrap
• account - The account that will sign the transaction

Returns

A transaction builder that can be used to build and sign the transaction

pub async fn unwrap( &self, amount: i64, account: &Account, ) -> Result<TransactionBuilder<'_, P>, ContractError>

Unwraps bNEO to NEO

Arguments

• amount - The amount of bNEO to unwrap
• account - The account that will sign the transaction

Returns

A transaction builder that can be used to build and sign the transaction

pub async fn claim_gas( &self, account: &Account, ) -> Result<TransactionBuilder<'_, P>, ContractError>

Claims GAS rewards from holding bNEO

Arguments

• account - The account that will sign the transaction

Returns

A transaction builder that can be used to build and sign the transaction

pub async fn get_rate(&self) -> Result<f64, ContractError>

Gets the current exchange rate between NEO and bNEO

Returns

The exchange rate as a floating-point number
