Take a snapshot of token stakers on a Cosmos-SDK chain. Purpose-built for Juno but probably works for other chains in the Cosmos ecosystem.
This program takes a number of flags and commands. Specifying --grpc is always
required as that is how the program reads on-chain data. To get a snapshot of
delegators staking JUNO with validators that are not jailed run the following:
cosmos-hodler-snapshot --grpc=<gRPC-URI> native-stakers
These results are written to a CSV file: ./juno_stakers.csv where amounts are
denominated using the native precision. In juno's case these are ujuno
(“micro-juno”) where 1000000ujuno is equal to 1 JUNO token.
NOTE: To snapshot the chain at a certain height spin up a Juno
node and halt it at the
desired snapshot height by setting halt-height=<HEIGHT> in the node's config.
This way a consistent snapshot is taken at a definitive height and no
inconsistencies will appear, as would be the case with taking a snapshot against
a live node that is actively consuming blocks.
Install Rust using rustup or however you like. Then just do cargo build;
nothing fancy here.
For an environment with nix installed one can run nix-shell to bootstrap a
dev environment without the need to fumble with rustup.
