FLOP devnet limits: faucet grants, miner and validator sponsorship caps

The public FLOP devnet rations three things: free test FLOP from the faucet, sponsored stake for new miners, and sponsored stake for new validators. On November 7, 2026 Flop Labs said it had "increased limits by 10x" and would do "another 10x" after more testing. This page lists the caps Flop now publishes and shows you where to read the live budgets yourself.

Devnet FLOP has no value and devnet work earns no airdrop weight. Nothing here is a route to the FLOP airdrop. It only tells you why a request might be refused and when to try again.

What are the FLOP devnet miner limits?

Flop's miner manual has a "Devnet limits" table. When we read it on November 8, 2026 it showed these values, ten times the figures in the earlier version of the manual:

Limit	Value now	Before the Nov 7 raise
New sponsored miners	At most 100 per rolling 24 hours	At most 10
Sponsored stake	At most 200 million FLOP per rolling 24 hours, new stake and top-ups together	At most 20 million
Stake per miner	Starts at about 1 million FLOP, top-ups to at most 2 million	Same
Sponsorships per account	One	Same
Sponsorships per approved operator	Its quota per role, counting every miner it has ever granted	Not listed
Public sponsor route	6 requests per minute per address (an IPv6 /64 counts as one)	6 per minute

The manual says requests past a daily limit "get 429 and nothing is registered". It asks you to check before you ask and back off when refused. Our devnet miner guide and miner setup guide cover the rest of the setup.

What are the FLOP devnet validator limits?

Flop's validator manual, updated November 6, 2026, says signed validator sponsorship requests "may auto-admit within the chain-backed sponsored count/stake caps" and that validators "no longer need the former sponsorship allowlist". The manual does not print the cap values. The live endpoint below does.

Flop Labs also said on November 7 that "stabilising requires rapid iteration on validators and we will be expanding cap slowly". Our devnet validator guide walks through the package and the onboarding steps.

How do I check the live FLOP devnet budgets?

The miner manual points to GET https://faucet.flop.network/limits, which it says "shows the live budgets, refreshed about once a minute". It is a public read-only JSON page. You don't need a wallet or a key to open it. Here is what it returned on November 8, 2026 at 10:33 UTC. These numbers move all day, so treat them as an example of what you will see.

Budget	Reading at 10:33 UTC, Nov 8
Miner sponsor: new sponsorships today	99 used of 100
Miner sponsor: stake budget today	119.6 million used of 200 million FLOP
Miner sponsor: capacity	179 of 256 slots used
Miner sponsor: automatic admission	Open, 64 uncalibrated miners of a 100 cap
Validator sponsor: new sponsorships today	0 used of 100
Validator sponsor: stake budget today	0 used of 150 million FLOP
Faucet daily cap	4.37 million used of 10 million FLOP
Faucet quick grant	25 FLOP, one per address every 24 hours
Faucet agent grant	2 FLOP every 24 hours, and a rollover requires spending

If the miner counter reads 99 of 100, a new request will probably be refused until the rolling window frees a slot. Check the endpoint first so you don't burn your per-minute allowance on requests that cannot succeed.

Why does Flop cap the devnet?

The manuals don't give a reason. In its November 7 replies, Flop Labs raised the miner limits after a devnet user said the sponsor miner kept hitting its daily limits, and it tied the slow validator expansion to "rapid iteration on validators". The devnet is a disposable test network that Flop is still tuning. Expect the caps to keep changing until the FLOP testnet date is announced.

FAQ

What are the FLOP devnet limits now?

Flop's miner manual, read on November 8, 2026, allows at most 100 new sponsored miners and 200 million FLOP of sponsored stake per rolling 24 hours. Both are ten times the earlier figures. Each account gets one sponsorship and each miner starts with about 1 million FLOP.

Why did my FLOP devnet sponsor request return 429?

A 429 means a limit was hit and nothing was registered. The manual says to retry after the daily window frees up. Check https://faucet.flop.network/limits first to see which budget is used up.

Did Flop raise the devnet limits?

Yes. On November 7, 2026 Flop Labs said it "increased limits by 10x" and would do another 10x after more testing. The miner manual now shows 100 miners and 200 million FLOP per 24 hours, up from 10 and 20 million.

Do FLOP devnet validators still need an allowlist?

No, according to Flop's validator manual updated November 6, 2026. Signed sponsorship requests may auto-admit within the chain's sponsored count and stake caps. Flop Labs says it will widen the validator cap slowly.

How much FLOP does the devnet faucet give?

The live limits endpoint showed a quick grant of 25 FLOP per address every 24 hours, and 2 FLOP for agents, on November 8, 2026. The faucet also has a daily cap of 10 million FLOP across everyone.

Does devnet FLOP count toward the airdrop?

No. Devnet FLOP has no value and devnet work earns no airdrop weight, per Flop's timeline FAQ. The airdrop is tied to the testnet. See our airdrop guide.
