Ronin Network occupies a unique position in crypto history — it’s both a successful example of application-specific blockchain design (high throughput, near-zero fees optimized for gaming) and the site of the largest bridge hack in DeFi history. Built by Sky Mavis (the Vietnamese studio behind Axie Infinity) to handle the transaction volume of Axie Infinity at its 2021 peak (2-3 million daily active players), Ronin processed millions of micro-transactions — breeding Axie NFTs, minting SLP tokens, settling PvP battles — that would have cost thousands of dollars in Ethereum gas. The Ronin bridge hack in March 2022, attributed to North Korean hackers (Lazarus Group), drained 173,600 ETH and 25.5M USDC ($625M total). Sky Mavis rebuilt the bridge, repaid affected users, and continued developing Ronin as a gaming-focused L2 ecosystem.
Why Ronin Exists
The following sections cover this in detail.
The Axie Infinity Problem
- Breeding an Axie: 2 Ethereum transactions. At $50 gas, that’s $100+ to breed
- Claiming SLP (daily earnings): $30-80 in Ethereum gas
- Players in Philippines/Vietnam earning ~$5-15/day of SLP were spending that on gas
Axie Infinity was economically non-functional on Ethereum mainnet for its actual user base (many of whom were from developing countries playing for income).
Ronin Solution
- Proof of Authority (PoA) consensus — fast block times (~3 second), extremely low gas
- EVM compatible — Solidity contracts, MetaMask-compatible
- Custom bridge — ETH, AXS, SLP, WETH bridgeable between Ethereum and Ronin
Result: Breeding an Axie cost $0.01 in RON. SLP claims were free. The economics worked.
The Ronin Bridge Hack (March 23, 2022)
The following sections explain how this works.
What Happened
- 4 Sky Mavis validators + 1 Axie DAO validator compromised
- With 5/9 signatures, hackers authorized fraudulent withdrawals
- Drained: 173,600 ETH + 25.5M USDC
- Total: ~$625M at time of hack
The vulnerability: Ronin used only 9 validators with simple majority (5/9) for bridge approvals. Sky Mavis had temporarily given the Axie DAO permission to sign on behalf of all Sky Mavis validators (for gas-free transactions program) — this permission was never revoked. Hackers accessed a backdoor private key via a phishing attack.
Discovery: The hack went undetected for 6 days — only discovered when a user tried to withdraw 5,000 ETH and found the bridge empty.
Aftermath
- US government sanctioned Lazarus Group addresses
- Binance froze $5.8M from the hack caught in transit
- Sky Mavis: raised $150M round led by Binance to repay affected users
- Full user reimbursement: completed 2022
Post-Hack Reconstruction
The following sections cover this in detail.
Bridge v2 (Upgraded Security)
- Changed threshold from 5/9 → 15/22 (70%)
- Multisig with time delays for large withdrawals
- Reduced Sky Mavis exclusive control — more external validators
Ronin v2 Architecture
- RON stakers vote for validators
- More decentralized than original PoA
- Still EVM compatible
- Bridge audited by multiple security firms
RON Token
RON is Ronin’s native token:
| Property | Details |
|---|---|
| Function | Gas fees, staking, governance |
| Validators | Stake RON to become validators |
| Delegators | Stake RON with validators, earn rewards |
| Ecosystem fund | Allocated for game grants and developer incentives |

Beyond Axie: Ronin as Gaming Ecosystem
Since 2022, Sky Mavis expanded Ronin’s vision from Axie-only to multi-game gaming ecosystem:
Games on Ronin:
- Axie Infinity Origins (Sky Mavis) — Axie battle card game
- Axie Infinity: Homeland (Sky Mavis) — Kingdom/city building
- Pixels — On-chain farming game; surged to 1M+ daily active users in 2024
- Lumiterra — RPG with DeFi elements
- Multiple third-party gaming studios
Pixels deserves special mention: it became Ronin’s breakout success beyond Axie, demonstrating that Ronin could host non-Sky Mavis games with genuine traction. At its 2024 peak, Pixels had more daily active wallets than Axie.
Ronin vs. Other Gaming Chains
| Chain | Approach | Examples |
|---|---|---|
| Ronin | Gaming-specific EVM sidechain | Axie, Pixels |
| Immutable X | ZK L2 for NFTs/gaming | Gods Unchained, Illuvium |
| WAX | Separate gaming blockchain | Alien Worlds |
| BNB | General L1, gaming dApps | Stepn |
| Polygon | EVM L2, gaming dApps | Planet IX |
Ronin’s advantage is focused identity: it is explicitly a gaming chain, not a general-purpose chain with some gaming.
How to Use Ronin
- Get ETH or USDC via
- Bridge to Ronin via bridge.roninchain.com
- Install Ronin Wallet (browser extension or mobile)
- Access Sky Mavis games at axieinfinity.com, app.pixels.xyz, etc.

Social Media Sentiment
Ronin’s story is complicated by the hack, which permanently stained the narrative. “Sky Mavis” and “Ronin bridge hack” are inseparable in crypto memory. The positive rebuild story — fully reimbursing $625M, expanding to 22 validators, and attracting multi-game ecosystem — is real, but trust in bridge security takes years to rebuild. The Pixels success in 2024 was a significant positive signal: it showed Ronin could host non-Sky Mavis games genuinely at scale, with organic (not P2E incentive-driven) user acquisition. Axie Infinity itself declined significantly from its 2021 peak but remains operational. The broader sentiment about Ronin is: it works for gaming (low fees, fast blocks), it has scars from the hack, and its future depends on whether the gaming ecosystem continues to grow beyond Axie. The RON token performance has been modest post-hack. It remains the most battle-tested and successful dedicated gaming blockchain despite the hack making it crypto’s most prominent security failure story.
