Support My Work

Voluntary support for open science, reproducible research, and research software maintenance.

All support is optional. The site does not store payment secrets, private keys, recovery phrases, or payment credentials. For small crypto support, USDT or USDC is usually easier than BTC on-chain. Please confirm the payment method, asset, and network before sending funds.

Crypto support

USDT and USDC are shown first for small support amounts. BTCPay and BTC on-chain remain available for BTC payments, but BTC can fail below dust thresholds. Confirm the asset and network carefully before sending; wrong-network transfers may be unrecoverable.

BTCPay BTC invoice

Self-hosted BTCPay POS for BTC invoices with user-entered amount.

Open BTCPay BTC POS

BTC on-chain payments below the dust threshold may fail in BTCPay. For small amounts, use USDT or USDC instead, or use a larger BTC amount.

crypto

BTC on-chain

Bitcoin mainnet address for larger manual BTC support. Prefer the BTCPay invoice link when you want amount entry and invoice tracking.
