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

Creates a new NeoXBridgeContract instance with the default contract hash

Arguments

• provider - An optional reference to an RPC client

Returns

A Result containing a new NeoXBridgeContract instance or an error

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

Creates a new NeoXBridgeContract instance with a custom script hash

Arguments

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

Returns

A new NeoXBridgeContract instance

pub async fn deposit( &self, token: &ScriptHash, amount: i64, destination: &str, account: &Account, ) -> Result<TransactionBuilder<'_, P>, ContractError>

Deposits tokens from Neo N3 to Neo X

Arguments

• token - The script hash of the token to deposit (currently only GAS is supported)
• amount - The amount of tokens to deposit
• destination - The destination address on Neo X
• 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 withdraw( &self, token: &ScriptHash, amount: i64, destination: &str, account: &Account, ) -> Result<TransactionBuilder<'_, P>, ContractError>

Withdraws tokens from Neo X to Neo N3

Arguments

• token - The script hash of the token to withdraw (currently only GAS is supported)
• amount - The amount of tokens to withdraw
• destination - The destination address on Neo N3
• 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_fee(&self, token: &ScriptHash) -> Result<u64, ContractError>

Gets the bridge fee for a specific token

Arguments

• token - The script hash of the token to get the fee for

Returns

The bridge fee as a u64

pub async fn get_cap(&self, token: &ScriptHash) -> Result<u64, ContractError>

Gets the bridge cap for a specific token

Arguments

• token - The script hash of the token to get the cap for

Returns

The bridge cap as a u64
