Oasys Data: Index Game Assets, Verses, and Players
Index Oasys Hub Layer and Verse Layer contract events, NFT and token transfers, and decoded player actions in one pipeline, delivered to your own database. Real-time and full history, no node to run.
Oasys started as a blockchain for games and now calls itself the blockchain for Asia and beyond. It is an EVM-compatible network built so studios can ship Web3 titles without making players think about gas. Its defining trait is a two-layer design: a Hub Layer that acts as a scalable Layer 1 backbone for tokens, NFTs, and bridging, and Verse Layers, game-specific Layer 2 rollups where the actual play happens. Game developers run their own Verse and cover transaction costs, so players get a gasless, fast-play experience. OAS pays for gas, deposits, and staking rewards and carries governance, while the validator set is drawn from major game studios. You can read how the team frames it at oasys.games.
That multi-layer, game-first design is the data problem. Oasys spreads activity across the Hub Layer and a fan-out of Verse Layers, all of them EVM, where mints, trades, transfers, and player actions stream out across many chains at once. Indexing Co covers the Hub and any Verse in a single pipeline, decodes the raw chains into the shape you want, and delivers it to your own PostgreSQL, warehouse, or webhook. Real-time and full history, with no node to operate.
Why Oasys data is hard
What Indexing Co delivers for Oasys
Stand up and maintain the whole stack yourself.
- Run a Hub Layer node and a node per Verse, or wire up third-party RPCs for each.
- Fetch and decode logs, traces, and receipts against the right ABIs.
- Track game contract upgrades and per-Verse event schemas by hand.
- Build backfill, reorg handling, and real-time delivery from scratch.
One pipeline sources, decodes, and delivers Oasys to your store.
- Hub Layer and Verse contract events, NFT and token transfers, and decoded txs in a single pipeline.
- Decoded data, shaped by your JavaScript transform.
- Lands in your PostgreSQL, BigQuery, warehouse, or webhook.
- Real-time delivery plus complete backfilled history. No node, no RPC babysitting.
What you can index
| EVM data type | On Oasys, for example |
|---|---|
| Contract events and logs | OAS staking and delegation, Verse game contracts |
| Token transfers (ERC-20, ERC-721, ERC-1155) | Game asset mints, in-game item trades |
| Decoded transactions and traces | Player actions across Hub and Verse layers |
| Protocol and account state | Marketplace listings, validator stakes, game balances |
A transform, not a subgraph
You write the transform in JavaScript, not AssemblyScript, and change it without re-indexing from block zero. Indexing Co runs your function over each block server-side: decode the logs you care about and return rows for your destination.
// Indexing Co transform: reshape each block into rows for your database
function transform(block) {
const results = [];
const signatures = [
'event Transfer(address indexed from, address indexed to, uint256 value)'
];
for (const tx of block.transactions || []) {
for (const log of tx.receipt?.logs || []) {
const event = utils.evmDecodeLogWithMetadata(log, signatures);
if (!event) continue;
results.push({
chain: block._network,
block: Number(block.number),
tx_hash: tx.hash,
contract_address: log.address?.toLowerCase(),
from: event.decoded.from,
to: event.decoded.to,
value: event.decoded.value,
});
}
}
return results;
}

FAQ
Do I need to run an Oasys node?
No. Indexing Co sources Hub Layer and Verse blocks, logs, and traces for you, including full historical data, so you never operate a node or babysit an RPC endpoint.
Can I index both the Hub Layer and a Verse?
Yes. Both the Hub Layer and the Verse Layers are EVM, so we index them the same way. Point a pipeline at Hub-side token, NFT, and bridge contracts, at a specific game Verse, or at both, and we decode the events against the right ABI.
Can I track NFT and in-game asset activity on Oasys?
Yes. We follow ERC-721 and ERC-1155 transfers, marketplace listings and sales, and mints and burns, so you can reconstruct ownership and asset flows across an entire game economy and across Verses.
Where does the Oasys data go?
Into your own destination: PostgreSQL, BigQuery, a warehouse, or a webhook. You define the output schema and own the storage.
Can I get complete historical Oasys data?
Yes. We backfill from your chosen start block and merge it with real-time data, so your Oasys dataset is gap-free from genesis forward if you want it.
