streamflow-sdk

用于与 Streamflow 协议交互的 Rust on-chain solana 程序的 SDK

用法

在程序 Cargo.toml 中声明依赖

streamflow_sdk = {version = "0.6", features = ["cpi"]}

要在主网中使用协议，请使用具有 mainnet 功能的 SDK

streamflow_sdk = {version = "0.6", features = ["cpi", "mainnet"]}

示例 anchor 程序调用 streamflow 创建指令

use anchor_lang::{prelude::*};
use anchor_spl::{
    associated_token::AssociatedToken,
    token::{Mint, Token, TokenAccount},
};

use streamflow_sdk;
use streamflow_sdk::cpi::accounts::Create;

let accs = Create {
    sender: ctx.accounts.sender.to_account_info(),
    sender_tokens: ctx.accounts.sender_tokens.to_account_info(),
    recipient: ctx.accounts.recipient.to_account_info(),
    recipient_tokens: ctx.accounts.recipient_tokens.to_account_info(),
    metadata: ctx.accounts.metadata.to_account_info(),
    escrow_tokens: ctx.accounts.escrow_tokens.to_account_info(),
    streamflow_treasury: ctx.accounts.streamflow_treasury.to_account_info(),
    streamflow_treasury_tokens: ctx.accounts.streamflow_treasury_tokens.to_account_info(),
    withdrawor: ctx.accounts.withdrawor.to_account_info(),
    partner: ctx.accounts.partner.to_account_info(),
    partner_tokens: ctx.accounts.partner_tokens.to_account_info(),
    mint: ctx.accounts.mint.to_account_info(),
    fee_oracle: ctx.accounts.fee_oracle.to_account_info(),
    rent: ctx.accounts.rent.to_account_info(),
    timelock_program: ctx.accounts.streamflow_program.to_account_info(),
    token_program: ctx.accounts.token_program.to_account_info(),
    associated_token_program: ctx.accounts.associated_token_program.to_account_info(),
    system_program: ctx.accounts.system_program.to_account_info(),
};

let cpi_ctx = CpiContext::new(ctx.accounts.streamflow_program.to_account_info(), accs);

streamflow_sdk::cpi::create(
    cpi_ctx,
    start_time,
    net_amount_deposited,
    period,
    amount_per_period,
    cliff,
    cliff_amount,
    cancelable_by_sender,
    cancelable_by_recipient,
    automatic_withdrawal,
    transferable_by_sender,
    transferable_by_recipient,
    can_topup,
    stream_name,
    withdraw_frequency,
    pausable,
    can_update_rate
)

Streamflow 协议

Rust 程序，提供 SPL timelock 功能

功能包括

• create 创建一个锁仓合约。
• update 更新一个锁仓合约
• withdraw 从一个锁仓合约中提款。
• cancel 取消一个锁仓合约。
• transfer_recipient 一个锁仓合约的接收者。

高级概述

费用

Streamflow 协议将合约总金额的 0.25%（净存款金额）转移到 streamflow 财务库，以覆盖构建和维护协议的费用。

在 Streamflow 协议上注册为合作伙伴

Streamflow 协议支持将合作伙伴费用集成到在 Streamflow 之上构建的其他协议。更多信息，请在 discord 上联系我们。链接
