Overledger Platform. The enterprise standard for building on blockchain.
Emit new event for transactions to/from a specific account.
Emit new event when a smart contract releases a new event.
Emit new event when a new column is added to a table. See the documentation
Emit new event when a row is added or modified. See the documentation
Emit new event when a new row is added to a table. See the documentation
Executes a signed transaction by sending it to a blockchain node via Overledger. See the documentation
Prepares a smart contract transaction for signing on the Overledger platform. See the documentation
The Overledger API by Quant Network allows developers to interact with multiple blockchain networks. It facilitates the creation, reading, and execution of smart contracts and transactions across different blockchains. This API simplifies the complex nature of blockchain interoperability, enabling multi-chain applications (MApps) through a single gateway.

On Pipedream, you can leverage the PostgreSQL app to create workflows that automate database operations, synchronize data across platforms, and react to database events in real-time. Think handling new row entries, updating records from webhooks, or even compiling reports on a set schedule. Pipedream's serverless platform provides a powerful way to connect PostgreSQL with a variety of apps, enabling you to create tailored automation that fits your specific needs.
import postgresql from "@pipedream/postgresql"
export default defineComponent({
props: {
postgresql,
},
async run({ steps, $ }) {
// Component source code:
// https://github.com/PipedreamHQ/pipedream/tree/master/components/postgresql
const queryObj = {
text: "SELECT NOW()",
values: [], // Ignored since query does not contain placeholders
};
return await this.postgresql.executeQuery(queryObj);
},
})
