\subsection{GraphQL Schema}
|
|
|
|
G-Chain exposes a unified GraphQL schema across all chains:
|
|
|
|
\begin{lstlisting}[language=GraphQL, basicstyle=\small\ttfamily]
|
|
type Query {
|
|
# Chain queries
|
|
chain(id: ChainID!): Chain
|
|
chains(filter: ChainFilter): [Chain!]!
|
|
|
|
# Cross-chain queries
|
|
asset(id: AssetID!, chain: ChainID!): Asset
|
|
crossChainTransfers(
|
|
from: ChainID!,
|
|
to: ChainID!,
|
|
after: Timestamp
|
|
): [Transfer!]!
|
|
|
|
# Address queries
|
|
address(id: Address!, chain: ChainID!): AddressInfo
|
|
addressBalances(
|
|
address: Address!,
|
|
chains: [ChainID!]
|
|
): [Balance!]!
|
|
|
|
# Advanced queries
|
|
pathBetween(
|
|
from: NodeID!,
|
|
to: NodeID!,
|
|
maxDepth: Int = 6
|
|
): [Path!]!
|
|
|
|
aggregateBy(
|
|
nodes: NodeFilter!,
|
|
groupBy: [String!]!,
|
|
aggregations: [Aggregation!]!
|
|
): [AggregateResult!]!
|
|
}
|
|
|
|
type Chain {
|
|
id: ChainID!
|
|
name: String!
|
|
blockHeight: BigInt!
|
|
totalTransactions: BigInt!
|
|
activeAddresses: BigInt!
|
|
tvl: BigInt!
|
|
}
|
|
|
|
type Asset {
|
|
id: AssetID!
|
|
chain: ChainID!
|
|
symbol: String!
|
|
decimals: Int!
|
|
totalSupply: BigInt!
|
|
holders: BigInt!
|
|
transfers: [Transfer!]!
|
|
}

\end{lstlisting}
