    How does AggLayer handle proof aggregation across rollups?

    I'm diving into the technicalities of AggLayer and its handling of proof aggregation. Specifically, does AggLayer function as a zk rollup chain itself, and how does it aggregate proofs from different rollup chains? Are these proofs merely treated as normal transaction data, or is there an aggregation proof algorithm employed, like Halo, Plonky2, or Nova? Additionally, how do rollup chain nodes verify these aggregated proofs—does this involve a contract deployed on Ethereum?

    How to complete token migration using Ledger?

    I'm trying to migrate my tokens from Ledger on the Polygon technology site, but Ledger isn't listed among the wallet options. Only MetaMask, Stargazer, or WalletConnect are shown. Can I complete the migration from Ledger, or do I need to use MetaMask or Stargazer?

    Does Polygon support developers building on its platform?

    I've been actively trying to build on the Polygon network, specifically working on minting collections. While there are many new collections being minted, it seems like there's not much visible support from the Polygon team for developers like us. Are there any support mechanisms or resources that Polygon provides for developers building and minting on their platform?

    How to unstake POL on Ledger with a Matic address?

    I'm planning to unstake POL tokens that I initially staked to a Matic address on my Ledger. Is there anything different I need to do during the unstaking process, or do I just unstake normally and have the POL tokens sent back to the original Matic address?

    How can I set up a local testnet with Heimdall and Bor?

    I'm trying to set up a local testnet with Heimdall and Bor for testing purposes. I’ve tried using ChatGPT and other resources but wasn't successful. It seems like the documentation available is focused on the mainnet. Can someone guide me on how I can perform these tests locally? I also attempted using different tools without success. Any help would be appreciated.

    Matic to POL Change on Matic Network: Do I Need to Act?

    I've noticed that my wallets with Matic on the Matic network have suddenly switched to POL. I'm curious if this affects anything in terms of gas fees or network functioning, and do I need to take any action regarding this transition?

    Why are my transactions included after 2 blocks?

    I'm running a node and I've noticed that my transactions are always included two blocks later rather than in the next block. I've checked online and found others with the same issue but no answers. Could it be due to peer connection problems? I even streamlined to new block creation, but the latency still results in my transaction entering in block n+2. Does anyone know why this is happening?

    Are custom polygon CDK chains fully EVM compatible?

    I'm working with custom polygon CDK chains and need to know if they are fully EVM compatible. Specifically, are there any opcodes not supported, and is there any difference in the outputs of global variables like block.timestamp and block.number compared to the Ethereum chain? Any documentation links on EVM compatibility would be greatly appreciated.

    How to map and deploy custom child tokens on Polygon?

    I'm trying to deploy root and child tokens on the Polygon network, but I'm unsure how to find the 'ChildChainManager' addresses for Polygon mainnet and Amoy. The documents don't mention them and the Google request form doesn't allow entering a child contract address. How can I communicate this for proper token mapping?

    Do MATIC token owners own ETH included in contracts?

    Hey there! I'm exploring the world of crypto and I've come across something curious in my Trezor Ethereum Explorer. Alongside my Contract Matic Token, there are some ETH tokens showing up. I'm scratching my head over who actually has ownership of these ETH tokens. Are they mine because I own the MATIC tokens, or do they belong to someone else entirely? Would appreciate some clarity on what happens to funds sent to a contract address by mistake.
