Payment Operations

The Synapse SDK uses USDFC (a Filecoin-native stablecoin) for storage payments. Before uploading files, you must fund your account and approve operators.

This guide covers the essential operations. For advanced topics (understanding rails, settlement strategies), see Rails & Settlement.

Before working with payments, familiarize yourself with these fundamental concepts:

Key Concepts

USDFC Token: Stablecoin on Filecoin which is used for all storage payments. The protocol requires USDFC approval before operations.
Payment Rails: Continuous payment streams created automatically when you upload files. Rate is fixed per epoch.
Epochs: Time periods (one epoch is 30 seconds). Payments accumulate per epoch and can be settled periodically.
Operator Allowances: Permissions that allow contracts (like WarmStorage) to spend your USDFC and create payment rails.

Account Management

Check Your Balance

Monitor your account balance to ensure you have sufficient funds for storage operations.

import { 
const TOKENS: {
    readonly USDFC: "USDFC";
    readonly FIL: "FIL";
}
TOKENS } from "@filoz/synapse-sdk";

var console: Console
The console module provides a simple debugging console that is similar to the
JavaScript console mechanism provided by web browsers.
The module exports two specific components:

A Console class with methods such as console.log(), console.error() and console.warn() that can be used to write to any Node.js stream.
A global console instance configured to write to process.stdout and
process.stderr. The global console can be used without importing the node:console module.

Warning: The global console object's methods are neither consistently
synchronous like the browser APIs they resemble, nor are they consistently
asynchronous like all other Node.js streams. See the note on process I/O for
more information.
Example using the global console:
console.log('hello world');
// Prints: hello world, to stdout
console.log('hello %s', 'world');
// Prints: hello world, to stdout
console.error(new Error('Whoops, something bad happened'));
// Prints error message and stack trace to stderr:
//   Error: Whoops, something bad happened
//     at [eval]:5:15
//     at Script.runInThisContext (node:vm:132:18)
//     at Object.runInThisContext (node:vm:309:38)
//     at node:internal/process/execution:77:19
//     at [eval]-wrapper:6:22
//     at evalScript (node:internal/process/execution:76:60)
//     at node:internal/main/eval_string:23:3

const name = 'Will Robinson';
console.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to stderr
Example using the Console class:
const out = getStreamSomehow();
const err = getStreamSomehow();
const myConsole = new console.Console(out, err);

myConsole.log('hello world');
// Prints: hello world, to out
myConsole.log('hello %s', 'world');
// Prints: hello world, to out
myConsole.error(new Error('Whoops, something bad happened'));
// Prints: [Error: Whoops, something bad happened], to err

Resolves once this transaction has been mined and has

This can resolve to null only if %%confirms%% is 0
and the transaction has not been mined, otherwise this will
wait until enough confirmations have completed.
wait();

Alternative: Two-Transaction Deposit (not recommended)

If you cannot use permit-based deposits, you can use the traditional two-transaction approach:

// 1. Approve USDFC spending
await usdfc.approve(paymentAddress, depositAmount);

// 2. Deposit
await synapse.payments.deposit(depositAmount);

This requires two transactions and higher gas costs. Use depositWithPermit instead.

Account Health Monitoring

Important: Monitor your account health regularly. Insufficient balance causes payment failures and service interruptions.

const err = getStreamSomehow();
const myConsole = new console.Console(out, err);

myConsole.log('hello world');
// Prints: hello world, to out
myConsole.log('hello %s', 'world');
// Prints: hello world, to out
myConsole.error(new Error('Whoops, something bad happened'));
// Prints: [Error: Whoops, something bad happened], to err

const name = 'Will Robinson';
myConsole.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to err
The console module provides a simple debugging console that is similar to the
JavaScript console mechanism provided by web browsers.
The module exports two specific components:

A Console class with methods such as console.log(), console.error() and console.warn() that can be used to write to any Node.js stream.
A global console instance configured to write to process.stdout and
process.stderr. The global console can be used without importing the node:console module.

Warning: The global console object's methods are neither consistently
synchronous like the browser APIs they resemble, nor are they consistently
asynchronous like all other Node.js streams. See the note on process I/O for
more information.
Example using the global console:
console.log('hello world');
// Prints: hello world, to stdout
console.log('hello %s', 'world');
// Prints: hello world, to stdout
console.error(new Error('Whoops, something bad happened'));
// Prints error message and stack trace to stderr:
//   Error: Whoops, something bad happened

Approving Operators

Operators are smart contracts authorized to spend your tokens for specific services. Before uploading files, you must approve the WarmStorage operator. This approval is required only once per operator and grants permission to create payment rails on your behalf.

Three types of allowances protect your funds from unauthorized spending:

Rate Allowance - Max spending per epoch across all rails
Lockup Allowance - Max total funds locked across all rails
Max Lockup Period - Max duration funds can be locked (the safety net)
