	Name
	ChainBootnodeRegistry() =default
std::unique_ptr< IBootnodeSource >	for_chain(ChainId chain_id) Return an IBootnodeSource for the requested chain.
std::unique_ptr< IBootnodeSource >	for_chain(uint64_t chain_id_int) Convenience overload that accepts a raw integer chain id.

Detailed Description

class discv5::ChainBootnodeRegistry;

Per-chain bootstrap seed registry.

Note: The returned source should be treated as a starting point. Always verify against the latest official sources before depending on these entries in production:

• Ethereum: https://github.com/ethereum/go-ethereum/blob/master/params/bootnodes.go
• Polygon: https://docs.polygon.technology/pos/reference/seed-and-bootnodes
• BSC: https://docs.bnbchain.org/bnb-smart-chain/developers/node_operators/boot_node
• Base: https://github.com/base-org/op-geth / https://github.com/base-org/op-node

Returns a concrete IBootnodeSource for a given ChainId. Data is sourced from officially maintained chain documentation and client repos, not from stale guesses; see comments on each chain's factory function.

Public Functions Documentation

function ChainBootnodeRegistry

ChainBootnodeRegistry() =default

function for_chain

static std::unique_ptr< IBootnodeSource > for_chain(
    ChainId chain_id
)

Return an IBootnodeSource for the requested chain.

Parameters:

• chain_id Numeric EVM chain identifier.

Return: Owning pointer to the source, or nullptr when the chain is not registered (caller should check).

function for_chain

static std::unique_ptr< IBootnodeSource > for_chain(
    uint64_t chain_id_int
)

Convenience overload that accepts a raw integer chain id.

Parameters:

• chain_id_int EVM chain id integer.

Return: Owning pointer, or nullptr when unrecognised.

function chain_name

static const char * chain_name(
    ChainId chain_id
)

Return the human-readable name for a chain identifier.

Parameters:

• chain_id Chain enum value.

Return: Name string (e.g. "ethereum-mainnet").
