Same big idea — no smart contract, an indexer reads it, open fair-launch minting — two very different chains. BRC-20 runs on Bitcoin's ~10-minute blocks and volatile fees. KRC-20 runs on Kaspa's sub-second BlockDAG for ~1 KAS a mint. Here's the honest side-by-side.
If you've minted a BRC-20 on Bitcoin, KRC-20 will feel instantly familiar. Neither uses a smart contract. In both, a token is created by broadcasting standardized deploy and mint operations that an indexer reads off the base chain and tallies into balances. And both made open fair-launch minting the default culture: a deployer sets a max supply and a per-mint limit, then anyone can mint until it's gone.
The difference is the chain underneath. BRC-20 lives on Bitcoin via Ordinals inscriptions — battle-tested and huge, but blocks land roughly every 10 minutes and fees swing hard when the mempool floods during an inscription rush. KRC-20 lives on Kaspa's BlockDAG, which targets sub-second blocks, so a mint confirms in seconds for a low, predictable fee of around 1 KAS.
KRC-20 isn't a fork of BRC-20 — it's a parallel evolution of the same "inscribe, don't contract" idea on a much faster base layer, given native token issuance at Kaspa's base layer after the Toccata upgrade. So the mental model transfers; the speed and fees don't.
The mental model transfers almost 1:1. If you get BRC-20, you already get most of KRC-20.
Neither standard makes you write or audit contract code. You broadcast standardized operations — BRC-20 as Ordinals inscriptions, KRC-20 as deploy/mint ops — and the network does the rest.
Balances aren't held in a contract. An off-chain indexer reads the inscriptions/operations off the base chain and computes who owns what — Bitcoin indexers for BRC-20, Kasplex for KRC-20.
Both popularized the same launch style: set a supply and mint limit, then open the floodgates. First come, first served, until supply runs out. Same hype, same countdowns.
Where the two standards actually diverge. Green marks the practical edge for a minter, not a verdict on which chain is "better."
| KRC-20 (Kaspa) | BRC-20 (Bitcoin) | |
|---|---|---|
| Base chain | Kaspa BlockDAG | Bitcoin |
| How a token is made | Standard deploy/mint ops, read by Kasplex | Ordinals inscriptions (JSON), read by an indexer |
| Smart contract? | No — set a few parameters | No — inscribe JSON |
| Block time | Sub-second (fast confirmation) | ~10 minutes per block |
| Typical mint network fee | ~1 KAS, low & predictable | Bitcoin fee — spikes with congestion |
| Transfer UX | Sign and send from your wallet | Traditionally a two-step inscribe-then-send |
| Launch style | Open, fair-launch minting | Open, fair-launch minting |
| Wallets | KasWare, Kastle (non-custodial) | Unisat, Xverse, OKX (non-custodial) |
| Live fairness grading | Yes — A–F on-chain via the radar | Not built in; varies by tool |
This is a simplification of common practice, not a rule — implementations and tooling evolve on both chains, and fees change with market conditions. Always verify current costs and a specific token's on-chain parameters before you mint.
On a hot launch, confirmation speed is the whole game. When supply mints out in minutes, a transaction that waits for the next ~10-minute Bitcoin block can miss the window entirely — and if you bump the fee to jump the queue during an inscription rush, you're bidding against everyone else doing the same. Kaspa's sub-second blocks mean a KRC-20 mint usually lands before the moment passes, at a fee that doesn't balloon under load.
The trade-off is honest: Bitcoin is the most secure, most liquid, most battle-tested chain there is, and BRC-20 inherits that. KRC-20 trades some of that lineage for speed and cost. Which matters more depends on what you're doing — but for the fast, cheap, high-frequency minting that fair launches reward, Kaspa's design is built for it.
One thing is identical on both chains: easy to launch cuts both ways. Low friction is as available to a rug as to an honest team, and for the first few minutes a fair launch and a pre-loaded one look the same. That's the exact problem our free Fair-Launch Radar solves for KRC-20 — it reads the pre-mint, mint progress, and holder spread off public on-chain data and grades every live launch A–F before you commit.

Instead of eyeballing an explorer, let the radar grade every live launch A–F on real holder distribution before you ape.
Whatever chain you come from, the tool you mint through takes a cut on top of the network fee — and the dominant Kaspa minting bots quietly take 5%. The Fair-Launch Radar mints the same on-chain KRC-20 for a flat 1.75%, non-custodial, so you sign from your own wallet. Over a wave of mints that gap is real KAS kept.
Same core idea — no smart contract, standardized deploy/mint operations read by an indexer, open fair-launch minting — but different base chains. BRC-20 lives on Bitcoin via Ordinals inscriptions, with ~10-minute blocks and fees that spike under congestion. KRC-20 lives on Kaspa's BlockDAG, which produces blocks in under a second, so mints confirm fast and typically cost ~1 KAS.
Mechanically they're close cousins — both avoid contracts and rely on an indexer reading inscriptions/operations off the chain, and both run on open fair-launch minting. KRC-20 isn't a fork of BRC-20, but if you understand BRC-20's deploy and mint flow, KRC-20 will feel familiar — just faster and cheaper because it runs on Kaspa, not Bitcoin. More on the standard: what is KRC-20. Coming from Ethereum instead? See KRC-20 vs ERC-20.
Typically yes on network fees. A KRC-20 mint pays roughly 1 KAS, and Kaspa's fees stay low and predictable thanks to high BlockDAG throughput. BRC-20 mints pay a Bitcoin fee that varies with mempool congestion and can spike during an inscription rush. Costs change with conditions — check both before minting. Separately, the tool's own fee matters: the radar mints KRC-20 at a flat 1.75% vs the bots' 5%.
KRC-20, by a wide margin. Kaspa targets sub-second blocks, so a mint confirms in seconds; Bitcoin blocks land roughly every 10 minutes, and transferring a BRC-20 traditionally needs a two-step inscribe-then-send. Fast confirmation matters most on a hot fair launch, where supply can sell out before a slow transaction lands.
Install a non-custodial Kaspa wallet like KasWare or Kastle (the KRC-20 equivalent of Unisat/Xverse), fund it with KAS, pick an open launch, and sign a mint — no separate inscription step. Vet fairness A–F on the radar first, then mint the open ones for a flat 1.75%, non-custodial.
Now you know how KRC-20 stacks up against BRC-20 — watch new Kaspa launches deploy in real time, check each one's fairness grade before you touch it, and mint from your own wallet at a flat 1.75%.
