Funding bot vs manual funding

Manual funding works when you are watching rates. A bot helps when offers go stale, FRR changes, or capital needs to be split across rates and loan periods.

  • FRR tracking and offsets
  • Funding offer cancel/replace flow
  • Rate spread and maturity ladder strategies
  • Paper mode before live offers

Safe API key setup

A funding bot should not need withdrawal permission. Stratum is built around scoped Bitfinex API keys for funding automation.

Auto-renew vs a real bot

Why Bitfinex auto-renew is not a funding bot

Bitfinex has a built-in auto-renew toggle that re-lends returned capital, but it re-offers at the same rate or at the FRR with no view of where the book actually is. When demand spikes, auto-renew leaves money on the table; when demand drops, it can sit unfilled. A funding bot watches the live funding book and decides at what rate, in what size, and for which loan period to offer next.

It reprices, auto-renew does not
Auto-renew re-posts the previous offer. Stratum re-prices against the current FRR and the depth on the book, so an offer that has gone stale gets cancelled and replaced instead of waiting.
It chooses the loan period
Auto-renew keeps offering 2-day loans. Strategies like Maturity Ladder and Yield Curve spread offers across loan periods to capture term premium when longer locks pay more.
It chases idle capital
Returned funding can sit idle for hours under a static offer. Stratum keeps unfilled capital working by re-offering as the rate moves rather than holding one price.

Repricing as the book moves

Funding rates on Bitfinex move minute to minute as margin traders open and close positions. An offer that was competitive an hour ago can be stranded behind newer, lower offers. Stratum runs a cancel-and-replace loop: it tracks the FRR and the visible offer book, and when your offer drifts out of range it cancels the stale one and re-posts at a rate that is set to fill, using the strategy you picked (FRR Offset, Rate Spread, Adaptive Spread, and others).

  • FRR-aware offsets that follow the Flash Return Rate up and down
  • Cancels stale offers instead of letting them sit behind the book
  • Strategies bias toward getting filled rather than holding out for a top tick that may never print

Offer laddering and the ~$150 minimum

Bitfinex enforces a minimum funding offer of roughly $150 equivalent, so dust and tiny balances can't be lent on their own. Rather than parking your whole balance behind one offer at one rate, Stratum can ladder capital across several offers at different rates and loan periods. Lower rungs fill quickly for steady utilization; higher rungs wait for demand spikes. Splitting also respects the per-offer minimum so each rung stays above the Bitfinex floor.

  • Keeps every offer at or above the ~$150 Bitfinex minimum
  • Spreads capital across rate and loan-period rungs instead of one flat offer
  • Low rungs fill for utilization; high rungs hold out for rate spikes

Bitfinex funding bot FAQ

What is a Bitfinex funding bot?

A Bitfinex funding bot automates lending offers in the Bitfinex funding market. It can place offers, cancel offers, and reprice based on strategy rules while funds remain in the lender account.

Can a Bitfinex funding bot withdraw my funds?

Stratum is designed for scoped API keys with withdrawals disabled. It should be able to manage funding offers, not move funds out of your Bitfinex account.

Is a funding bot the same as a lending bot?

For Bitfinex users, yes. Margin funding is the lending side of the Bitfinex platform, so people use funding bot, lending bot, and margin funding bot to mean similar things.

Does Stratum guarantee a higher APR?

No. Funding rates, fills, and platform risk vary. Stratum automates execution and reporting; it does not guarantee returns.

What is the minimum amount I can lend with a Bitfinex funding bot?

Bitfinex requires a minimum funding offer of roughly $150 equivalent per offer. Stratum keeps each offer it places at or above that floor, and when it ladders capital across several rates it sizes each rung to stay above the minimum.

How is this different from the Bitfinex auto-renew toggle?

Auto-renew re-lends returned capital at the same rate or the FRR with no view of the book. A funding bot reprices: it cancels offers that have gone stale and re-posts at a rate set to fill, and it can spread offers across loan periods instead of always re-offering 2-day loans.

What happens if a loan is returned early?

Bitfinex funding can be returned before the end of its term when the borrower repays or the position closes. When capital comes back, Stratum re-offers it under your active strategy instead of leaving it idle, so it goes back to work at the current rate.

How often does the bot reprice my funding offers?

Stratum watches the FRR and the visible offer book and reprices when your offer drifts out of range, rather than on a fixed timer. If the book has not moved, your offer stays put; when it does move, stale offers are cancelled and replaced.
